Was thinking about your post kindred/hyp. cos, a friend gave me a cd by Jane Parker who is a local (ish) jazz singer. Shes pretty good. Very jazz. There are a few singers around, you would get more gigs and still be able to play in the style you like,with one on board. mix vocal toons with instrementals you could. I have a bunch of friends who used to play impro modern jazz fusion whatyoumacalit at Cafe Cairo clapham north. had the place not burned down ....would have been a place to approach. But I'll contact them and see if theyve got any recomendations. so yeah, saying, could be a singer might help.
