Got the Wilson today. The vocals are not in the least annoying. On the contrary: Nan Wynn is such a sweet voice! And Pee Wee Russell plays some equally sweet solos on some of the tracks with her. So many great swing musicians in that collection!
I'd have to listen to it again, but on the spot cannot recall any Tolliver solos - Ayers, Laws, Bartz, Hancock - but no Tolliver. He solos nicely a few times on Ayers' first Atlanttic album, Virgo Vibes.
Agree on Hubert Laws. That cover was meant to illustrate the title, not the session personnel. Sharrock was Ayers' bandmate with Herbie Mann, who even had Linda sing on some gigs as you can hear on the recently issued tracks from the Whisky A Go Go.
The guy on the low right looks more like Billy Cobham to me. He played on a Mann-produced Ron Carter album on Embryo, that also featured Tate.
