NIGHT 2 of the FD-19 "Dollar Bill" weekend. Created at the human gate 2026-08-06: FD-19 covers TWO Avalon nights and only the Friday had a row, so this Saturday rendered on no day page. COAU FD_Shows gives four distinct Family Dog entries for this weekend, and they are the whole point: Aug 5 AVALON -- Big Brother & the Holding Company / Oxford Circle [FD-19] (event 62) Aug 5 LONGSHOREMEN'S -- Bo Diddley / Sons of Adam [FD-20] Aug 6 AVALON -- Bo Diddley / Sons of Adam [FD-19] (THIS ROW) Aug 7 LONGSHOREMEN'S -- Bo Diddley / Sons of Adam / Little Walter [FD-20] (event 320) Independently corroborated by the FAMSF catalog title for FD-20, which reads "August 5 & 7, Longshoreman's Hall, August 6, Avalon Ballroom" -- the Avalon night is SANDWICHED between the two Longshoremen's nights, not appended after them. So the two posters interlock: FD-19 holds the Avalon on Fri+Sat with different headliners each night; FD-20 holds Longshoremen's on Fri+Sun. Bo Diddley plays three of the four. Designers Mouse & Kelley on both sheets. This is why the FD-19/FD-20 "numbering swap" confusion exists in casual sources -- FD-19 genuinely does advertise Bo Diddley, just on its Saturday side. Unfeatured: 08-06's hero is BG-21 (Love, closing night at the Fillmore) -- the Graham-vs-Family-Dog rivalry that anchors that day.
