The Beatles 2
I think the children of the beatles should start a band. You have Sean Lennon on the left here and Dhani Harrison on the right.
This is Zak Starkey, Ringo's son.
And finally James McCartney, son of Paul.
James, Sean, and Dhani all play guitar and Zak plays drums. Now they just need to get someone to switch to bass and they'd be in business.
