I was just listening to you and Jeff Beck do a live "Love Me Do"/"Jean Genie" medley. You and Earl Slick should do that as a duet. It's fun.
Duets can be tricky. When duets are live and somewhat spontaneous, they are always exciting. When they are canned in the studio and the two artists have not actually sung together or even been in the same city for the project, duets can be tedious.
You've done some splendid duets: Cher, Marianne Faithful, Freddie Mercury, Annie Lennox, Gail. The list goes one. (Annie Lennox is touring with Sting, do you think they sing a duet of "Under Pressure"?)
I quite like the video of "Dancing In The Streets" you did with Mick Jagger. The song could have been done a bit better, but that doesn't seem to be the point of that duet: it was fun. It is clear that the two of you are having a good time performing together. I know that many of your superfans poo-poo it, but I will always adore it.
So, are there any surprise duets coming-up on this tour? I heard you sang "Station To Station" in Kansas City! Touche! old man!
Anyway . . . I think you should record a "Love Me Do"/"Jean Genie" medley in the studio. I think it could be a hit single. Get Tony Visconti and George Martin to produce it together and it could become by a media feeding-frenzy. Release it on John Lennon's birthday this Autumn, and have a big shindig with Yoko Ono and Ringo Starr and Mick Jagger (please do not invite Paul McCartney -- he's so dull he makes Sting look exciting!). It could be a benefit performance for some children's charity.
Go for it!
P.S.: Why are you endorsing Nestle? Don't you know there is a boycott?
