Sunday afternoon in this county offers two blues shows that both start at two o’clock, both cost ten dollars, and both run on the second Sunday of the month as a matter of standing habit rather than as anything anyone announced this week.

One of them takes place in a golf clubhouse. The other takes place on the lakefront acreage where Woody Guthrie wrote the final draft of his autobiography, and the difference between those two rooms is most of what is interesting about the afternoon.

The clubhouse is Royal St. Augustine Golf Club at 301 Royal St. Augustine Parkway, where the St. Augustine Jazz Society has hosted a blues jam on second Sundays from 2 to 5 p.m. for long enough that the society itself, founded in the 1990s, describes it as a standing arrangement in which “members of the Jazz Society take turns leading and choosing the songs.” Admission is ten dollars at the door. The society says on the same page that it has raised more than $100,000 for scholarships for local music students, which is a sum worth putting beside the cover charge, because a ten-dollar door in a clubhouse is the machinery that produced it. The band listed for Sunday is the Mojo Healers, a Jacksonville four-piece that the calendar describes as working the three surrounding counties at pubs, fairs, festivals and clubs.

The other room is Beluthahatchee Park, 1523 State Road 13 North in Fruit Cove, which is four acres of county park inside the 70-acre tract that Stetson Kennedy bought in 1948, three years after Mill Creek was impounded to make the eighteen-acre lake the bluffs look down on. The Duffy Bishop Band plays there from 2 to 4 p.m. Sunday, and the listing prices it at a ten-dollar suggested donation, which is the softest of the two doors and the only one that will let you in for nothing if nothing is what you have.

What the county owns, and what it does not say it owns

The park page St. Johns County publishes for Beluthahatchee is unusually forthcoming for a parks listing, and what it is forthcoming about is literature rather than picnic tables, although it gets to the picnic tables eventually.

It records that the final draft of Guthrie’s autobiography, Seeds of Man, and eighty songs were composed while he was in residence there as Kennedy’s frequent house guest, and that almost all of them had to do with a sense of place and with human rights issues drawn from Kennedy’s writings. It records the 2003 nomination by the Florida Center for the Book and the Council for Florida Libraries under which Friends of Libraries USA designated Beluthahatchee a Literary Landmark, number 83 in that register. It records that when Kennedy subdivided the tract in 1949 he wrote restrictive covenants setting land aside in perpetuity as a wildlife refuge and requiring that houses be built consistent with his goal of “serving as a working demonstration that human and natural habitat need not be mutually exclusive, but can coexist in harmony.”

It gets to the picnic tables in the end, listing nature trails, picnic pavilions and parking, and giving the hours as dawn to dusk. What it does not do anywhere is mention that a concert series runs there, which is the ordinary condition of county park pages and is worth knowing before you drive up State Road 13 expecting to find a posted schedule.

The series has a name and it belongs to the Stetson Kennedy Foundation, which calls it Second Sundays at Stetson’s and describes it on its own front page as “a monthly concert series showcasing artists in-line with the causes of Stetson Kennedy.” The Foundation’s events page carries the same standing entry, worded as every second Sunday of the month, and the dated announcements on that page run to 2016, so the cadence is documented there and Sunday’s particular date is not. The date, the hours, the act and the ten dollars all come from the county-wide listing calendar, which takes submissions from venues and musicians and is a good place to learn that something is happening and a poor place to confirm it.

The band

Duffy Bishop has been working this kind of room a long time. The listing describes the group as a blues rock ensemble led musically by Bishop’s longtime musical partner and husband, Chris Carlson, with the two of them building ensembles around the duo wherever they tour, which they have done nationally and internationally. Her eighth studio album, Find Your Way Home, came out in 2014, and she holds the Cascade Blues Association’s female vocalist award.

If Sunday does not work, the same band is booked into St. Benedict the Moor on Saturday, Oct. 24, from 6 to 8 p.m. for the St. Benedict Blues Festival, at ten dollars, which the listing notes includes parking while any remains.

And the rest of Sunday

Roughly thirty live music listings sit on the county calendar for Sunday, the two blues afternoons among them, and the useful thing about the rest is how early in the day they start. David Watt Besley is at the BoatHouse at 11 a.m. and ZaZa Flamenca is at Casa Monica at the same hour. Gabby Samuels opens Mill Top at noon and Scott Halls takes the 4:30 slot there, which is that room’s standing three-a-day pattern. Jolie is at Bin 39 at one and Arvid Smith takes the same bar at seven.

Colonial Oak is the one place with a lineup published by the people who booked it. Sunday closes the festival’s second weekend there with four free sets, the festival’s own page naming Angel Chantel and Underbrush at 3:30, Bob Patterson at five, the Palmetto Pickers Band at 6:30 and Gypsy Strings Revival at eight, under the heading “Local Artist Showcases - FREE EVENT!” The festival’s third and final weekend runs Sept. 18 to 20.

So the free music on Sunday is on St. George Street and the ten-dollar music is out on the water and out on the parkway, and both of the ten-dollar rooms start while the light is still good.
