The singers were part of a chorus which also included Josh Groban, performing at the finale of If I Loved You: Gentlemen Prefer Broadway, a stage show co-curated by Wainwright, during which he dueted with other male vocalists on Broadway classics.

Wainwright released ‘Vibrate: The Best of Rufus Wainwright’ earlier this year. The 18 track collection came alongside a bonus disc that featured 16 rare tracks, recorded both live and in the studio, including songs laid down at his London Kenwood House show in 2010 as well as ‘The Maker Makes’ from the film Brokeback Mountain, ‘La Complainte de la Butte’ from Moulin Rouge and new song ‘Chic and Pointless’.
