Elton John was joined by British rapper Plan B for a collaboration at the Radio 2 Electric Proms.

Playing at the Camden Roundhouse, John was on the piano while Plan B took vocals for a rendition of the classic hit, ‘I Guess That’s Why They Call It The Blues’.

They were joined by a six piece band, a brass section and four backing singers.

Introducing Plan B, John said: “When I was asked to do this programme I got to choose two guests.

“The first is from my favourite album of the year ‘The Defamation of Strickland Banks’. Ladies and Gentlemen, Plan B.”
