For myself as well as others Bob Relf not only brought the house down but was the subject of conversations for months afterwards. Otis Smith of course even if the Catacombs has first claim the memories of it's first play at then Mecca are still with me.
After that there's a whole host. Timothy Wilson's version of 'itching' doesn't get much of a mention but went down great. Detroit Sound Jumping at the Go-Go, Sons of Moses, Bobby Treetop, Little Joe Cook, Reperata's Panic, first heard Lorraine Ellison's Call Me Anytime there Lou Pride which other places laid claim to but a first for me there. Linda Jones Just Can't Live My Life just blew me away as it did the rest. Bobby Patterson My Baby's Coming Back, Lillie Bryant, Gwen Owens, Little Johnny Blair and keeping with the funkier side I always enjoyed Ladies Choice.
So stretched the point a little perhaps not all Mecca firsts but first for me and to get that lot mixed in with some of the top notch sounds already playing elsewhere meant it was a good time to be around.
