Afaik David Byrne and Gary Numan both claim to be autistic, though I dunno if they've been formally tested.

David Byrne is the lead singer of Talking Heads. Try watching something like his Stop Making Sense self-interview or True Stories.

I dunno about much about Gary Numan except that he was a pioneer in New Wave and electronic music in general; as well as the frontman for Tubeway Army (check out the album, Replicas).
