The Zimmers Rock It Old-School

Reeaaaaaal old school. As in, the British singing group's average age is 78. The 40-member senior chorus performs a few well-picked covers (The Who's "My Generation" and a twist on a Beatles tunes, "When I'm (One Hundred and) Sixty-Four"), according to The Washington Times. It's like when TDA squeezer emeritus Clyde Forsman sang Jimi Hendrix's "Fire" and Rod Stewart's "Da Ya Think I'm Sexy," only times 40.

Now the Zimmers are riding a wave of buzz to America. (The well-produced YouTube video below has been watched more than 2 million times so far.)
