The Roots have pulled out of two David Bowie tribute nights - the same ones that Michael Stipe appeared on Fallon to promote the other night - at the 11th hour because of what drummer and band leader Questlove called 'bitchassness'.

He took to Instagram to allege that there has been petty behaviour amongst an unnamed fellow musician who would not allow them to share their equipment on the night.

As a result, the band have pulled themselves from the show.

He said in the caption for the photo below: "I've never been so insecure or petty as to deny a fellow musician use of any of my equipment (or my band's equipment or resources or contacts or knowledge or anything) it angers me when that same courtesy is not reciprocated."

"Keeping a level head and not being self destructive is a weak point I'm working on. But I'm also keeping it true... We have patience. But we do not have patience for the #Bitchassness. Enjoy your precious equipment."

Other acts on the bill for tonight and tomorrow's shows at Carnegie Hall and Radio City Music Hall include Pixies, Debbie Harry, Michael Stipe, Rickie Lee Jones and The Flaming Lips tonight; and tomorrow, Mumford & Sons, Blondie, Pixies, Michael Stipe and many more.
