Don't worry....

Yoko Ono performing at the opening of this year's Meltdown Festival on London's South Bank, with the Plastic Ono Band led by Sean Ono Lennon. The band were very tight, mainly Japanese these days, with women on drums, bass and keyboards. They finished with Don't Worry Kyoko (Mummy's Only Looking for Her Hand in the Snow).

Yoko turned 80 in February, still seems pretty energetic...
