Aerosmith Performs “Legendary Child” on Idol’s Finale [AUDIO]

On last night's season finale, judge Steven Tyler performed with his band Aerosmith. The longtime and much loved rockers debuted their brand-new single, ‘Legendary Child.’ The song is a rager, and Tyler, best known on the show for his clever, from left field one-liners, was in full on rock star mode once he got in front of that crowd.

The band also rocked through the classic hit ‘Walk This Way,’ which has history with popular music, as rap act Run-DMC sampled it in the ’80s.

For five minutes, Aerosmith turned the ‘Idol’ stage into a full on rock show.

Here is the studio version for your listening enjoyment.
