"I feel like the neatest kid on the block," says rock singer-composer Stephen (On and On) Bishop, 26—and why not? Grouped round to say hi after his recent gig at Los Angeles' Roxy Theatre were a gang who call themselves "Stephen's Ladies"—no lesser songbirds than (from left) Natalie Cole, Donna Summers, Joni Mitchell and Chaka Khan (who sings back-up on his album Careless). But Stephen makes no romantic claims on his Ladies. They're all just funky neighbors from Laurel Canyon, he explains.
