Tennis this weekend at Golden Gate Park -- at same time as "Hardly Strictly Blue Grass" festival?

Any one interested in playing tennis in Golden Gate Park this weekend (October 4th [SAT] and 5th [SUN]) while the Hardly Strictly Blue Grass Festival is going on at the same time?  

Sure . .  it'll be heck getting to GG Park and finding parking . . .

. . . but tennis and nice (loud) music nearby should make for a fun time . . . bring food (drinks?) ::: so, if we get enough people, say 6 persons (3 doubles team round-robin style) sharing a court, with those not playing sitting down and enjoying munchies, etc.
