I think that's Ruffneck's "All That Jazz" on MAW, which I heard Derrick May play a few times around 1998.
Jonny. > Right, I've got this tape mixed by Derrick May at Simon's in Gainsville (I believe 1998), somewhere around 50min he plays 'Silvery Sounds' by Sound Of K on Fcom, right after that he plays this track which is kinda the ultimate party track: a kind of jazzy, big band bass line and this female scatting voice over top talking about the moo-moo blues in an incredibly fast way, what the hell is this track?!
