After Devo floated their first demo around, there was a feeding frenzy over who would sign them and who would produce them.
(In the end, Brian Eno and Warner Bros won out.)
Bowie even offered to create a brand new record label for them if he could produce.
But during this whirlwind, billionaire entrepreneur Richard Branson flew the band to one of his mansions on one of his private islands and (according to one Devo bio penned by Gerald Casale and Mark Mothersbaugh of the band) smoked them out on incredible weed which near-incapacitated them, then told them he was prepared to sign them IF they would agree to let John "Johnny Rotten" Lydon (ex-Sex Pistols/pre PiL, who was allegedly waiting in another room) to be their singer and frontman.
According to the story, the band members could do nothing but laugh hysterically in response.
I get the impression the rest of their meeting with Branson was rather awkward.
On a similar sort of note, after Jim Morrison died and after The Stooges imploded, the idea of Iggy Pop fronting The Doors was kicked around, and he spent some time with the surviving members and trying it out. I think it was mutually but amicably decided that it didn't mesh that well.
