The compilers of a new John Lennon covers album for charity have been so inundated with artists who want to appear on the project, they haven't been able to fit them all on the double CD.
U2, Green Day, R.E.M., Avril Lavigne, Big + Rich, Christina Aguilera and Snow Patrol are among the artists who have made it onto 23-track album Instant Karma: The Amnesty International Campaign to Save Darfur.
But acts like Duran Duran, Ozzy Osbourne and Willie Nelson all missed the cut.
In total, album organisers had 50 Lennon renditions to work with.
The 30 acts who missed out on an album place will feature as digital downloads via online retailers.
Human rights organisation Amnesty International is the brains behind the project and Lennon's widow Yoko Ono has waived her royalty fees.
A spokesman for the charity says, "The Instant Karma mobilisation centres on saving the lives of innocent women, children and men who are dying by the thousands and restoring peace in the region.
"Amnesty International chose to harness the power of Lennon's music to inspire a new generation of activists to stand up for human rights."
All proceeds from CD and digital sales will support Amnesty International.
Ono is thrilled with the response from her music peers: "It's wonderful that, through this campaign, music that is so familiar to many people of my era will now be embraced by a whole new generation."
