Saturday, September 7, 1968 was night two of the James Cotton Blues Band at the Avalon, with the Sir Douglas Quintet, Pulse and Womb, on FD-136.

James Cotton had played harmonica in Muddy Waters's band for a dozen years before taking his own name to the top of bills like this one — part of a steady migration of Chicago blues players onto the West Coast ballroom circuit that runs through this whole chronicle. The Sir Douglas Quintet beneath him were Doug Sahm's Texans, relocated to California and a fixture of both halls across four years.

FD-136 is the second and last sheet Weil drew for the Family Dog. He had made FD-135 the previous weekend, the white-on-black engraving for the Youngbloods, and after this one his name does not appear again. Two consecutive Avalon weekends in the late summer of 1968 is his entire documented output.

That is worth recording rather than passing over. The poster series is remembered through Wilson, Mouse, Kelley, Moscoso, Griffin and Conklin, and it was made by considerably more hands than that — Weil, Jack Hatfield, Bob Schnepf, Jerry Wainwright, John H. Myers, Tom Glass. Most of them appear once or twice and are known now by a catalog number.
