Well, here's a sight you don't see every day.
Aerosmith are currently on tour - and tonight they play Vilnius, the capital of Lithuania.
And while Steven Tyler and co. have been enjoying the sights of said city (with a camera crew, by the looks of things), this happened.
Check out Tyler joining in with two buskers who started playing the Aerosmith tune 'Crazy' when they saw him... Although 'joining in' is a slightly loose term. We do hope Mr Tyler hasn't forgotten the words to his own song!
