If you want to hear more "traditional" style vocals coming from Frank Zappa, then you should consider The Mothers "Fillmore East, 1971" or even "Cruising With Ruben and the Jets". Fillmore is a truly fun to listen to album that features Howard Kaylan and Mark Volman, aka Flo & Eddie, who were the lead singers with the pop band The Turtles. Ruben is a carefully crafted recreation of a 50's Do-Wop band sound that actually fooled people into thinking it was a real band. On both albums the vocals are somewhat stylized, but what elements of Zappa aren't?
BTW, "Willie the Pimp" is a great vocal done by Capt. Beefheart. If you think Zappa is out there, then Beefheart is from another solar system.
