It's one thing if you're new to the music industry to forget a few lyrics but it's another when you've sung a song hundreds of times before. Recently Steven Tyler completely blanked when he went to sing the lyrics for Aerosmith's hit 'Crazy' when caught off guard by a pair of Lithuanian street performers. So no, the frontman wasn't in a stadium filled with thousands of screaming fans when he flaked but none the less he completely forgot the words to his own song! Take a look at the video below. The clip shows Tyler blank out when the accordion player and violinist start recreating the 1994 smash hit.Take a listen for your self…sympathy or empathy either way Steven needs to brush up on his songs before continuing their world tour!
