Axl Rose sings on an upcoming charity song also featuring Elton John, and a bevy of other stars. The Who drummer Zak Starkey posted that he and GNR bassist Duff McKagan “cut bass for a cover of t.rex children of the revolution”. Later, his dad (Ringo Starr) added drums and Slash played guitar, before “Axl killed it – amazing vocals”. There are plans for an entire album.
