I've always wanted him to just do a girl group and teach them how to sing harmony like the Beach Boys did. Even a new girl group, the Pussycat dolls or somebody... if you listen to any of these girl groups that have been out the last 15 years or whatever, they don't know how to sing multi-part harmony. They just sing the same melody line, and one of them sings lead. So they'll have 4 or 5 girls singing the exact same thing
Have you heard the Staves, Ron? They're a British folky pop group that sings harmony very well--you might want to look into them. Not the greatest band out there, but not at all bad. Very good live, too.
