Aerosmith Kept A-Rockin At Surprise London Gig

US rock giants Aerosmith played an intimate secret gig at London's Hard Rock Cafe last night.

Steven Tyler, Joe Perry and co were in town to announce their London Hyde Park Calling concert, that will take place on June 24 - and they wowed the crowd of 150 lucky fans with 13 tracks from their huge back catalogue of hits.

The Hard Rock Cafe was sweltering by the time Steven Tyler stripped down to the waist before donning a black leather waistcoat.

Uncut's highlight of the heavy blues-laden night was a superb drawling rendition of 1975 single "Sweet Emotion." It sounded amazingly fresh considering it was written over 20 years ago.

They even chucked in a brilliant cover of Fleetwood Mac's "Rattlesnake Shake" - complete with marracas!

Aerosmith's full set list was:

Walkin' The Dog
Love In the Elevator
Livin' On The Edge
What It Takes
Draw The Line
Rattlesnake Shake
Don't Wanna Miss A Thing
Baby, Please Don't Go
Sweet Emotion
Cryin'
Mother Popcorn
Walk This Way
Train Kept A-Rollin'
