You're either gonna love or hate this one....
Dave Grohl and Foo Fighters recently performed in BBC Radio 1's Live Lounge, where they smashed out three wicked songs - The Sky Is A Neighborhood, Best of You and a cracking cover of AC/DC's Let There Be Rock.
Fast-forward two days later, and old mate Chris Martin from Coldplay is playing in the Live Lounge. And the smart buggers at the BBC recorded Grohl asking Martin a question - what's you favourite AC/DC song?
Martin quickly replied Thunderstruck - not a bad choice at all - and then gave a little demo of the tune....on piano.
Hmmm. The jury's still out on that one.
Have a watch below.
