The Who did a rare surprise club show Tuesday night in London when they took the stage at Porchester Hall in the Bayswater section of London to do a medley of “Baba O’Riley,” “See Me, Feel Me” and “Listening to You.” It was filmed and will be shown on Friday’s Stand Up to Cancer telethon this Friday at 8 p.m. ET on ABC, CBS, NBC and FOX. To get their short set right, they ran through it three times with each one being slightly different.

Roger Daltrey is a patron of the Teenage Cancer Trust and co-founder, along with Pete Townshend, of Teenage Cancer America.
