See Benedict Cumberbatch Sing 'Comfortably Numb' With David Gilmour

Former Pink Floyd rocker is playing stretch of shows at London's Royal Albert Hall

David Gilmour enlisted Benedict Cumberbatch to sing "Comfortably Numb" at Royal Albert Hall.

Sherlock actor Benedict Cumberbatch joined former Pink Floyd singer/guitarist David Gilmour onstage at the Royal Albert Hall Wednesday evening for the song "Comfortably Numb." Gilmour is in the middle of a series of five shows at the London venue in support of his 2015 album Rattle The Lock.

Cumberbatch sang conversationally. He accentuated a few lines with theatrical expressions. In between verses, he stood modestly as lasers and Gilmour's guitar pyrotechnics flashed around him. After delivering the line, "That'll keep you going through the show/ Come on, it's time to go," the actor ceded the stage to Gilmour.

Cumberbatch is no stranger to the musical world. In 2013, he recorded a song titled "Can't Keep It Inside" for the August: Osage County soundtrack, alongside renowned musicians like Bon Iver and Kings of Leon.

Gilmour will perform at Royal Albert Hall on September 29th and September 30th.
