Costello has performed on Letterman’s show 27 times, and was asked by the TV host to make a final appearance before he finishes his stint as the long-running compere of the programme. Costello performed a medley of ‘When I Write The Book’ and ‘Every Day I Write The Book’ during his appearance.

Letterman will step down as host of the long-running US late night talk show in May, and has secured an illustrious list of musical guests to coincide with his final broadcasts. Musical guests will include Mumford And Sons, Elvis Costello, The Dave Matthews Band, John Mayer, Iron & Wine, Ben Bridwell of Band of Horses, the Avett Brothers and Norah Jones. It’ll also stand as Tom Waits’ first live performance in two years.

Letterman has hosted The Late Show on CBS since 1993, prior to that hosting the similarly titled Late Night With David Letterman, which began in 1982. He will be replaced at the helm by Stephen Colbert, who currently presents Comedy Central’s The Colbert Report.

Colbert said of his appointment: “Simply being a guest on David Letterman’s show has been a highlight of my career. I never dreamed that I would follow in his footsteps, though everyone in late night follows Dave’s lead.”
