The circulating filesets labeled OAITW 4/16/73 early show (or s1) at the Boarding House are not correctly dated. But many person-hours of puzzling over many fragments of tape leaves us unclear as to to which ca. April 1973 OAITW gig this belongs. We know it is not 4/16/73. We know it is not 4/27 or 4/28/73 (thanks, OSF). We thought it might be the set I to match the set IIs we show for 4/19/73 and 4/20/73 at the Share, but that would produce duplicate songs and we don't think that'd be right. So, we remain stumped.
