Some have suggested they should be locked in a room together with musical instruments in order to force them to create a masterpiece that would pay tribute to their fathers. Besides the ethics, there is one major challenge that will prevent them coming together...
James McCartney is an avid musician who has released a couple of EPs, but he has admitted that it is unlikely they would ever come together to form a band.
The idea reportedly been discussed before between himself, Dhani Harrison, Sean Lennon but unfortunately, the idea doesn't appeal to Ringo Starr's son Zak Starkey.
Maybe locking them in a room isn't such a bad idea afterall?...
