Here is a thing: Tony Bennett and Lady Gaga (who appears to be rocking that suddenly visible Spring 2012 blue hair trend?) have recorded a duet of show tune standard “The Lady Is A Tramp.” Gaga’s voice sounds fine (if not a little Christina Aguilera-y/needlessly melismatic) and then they start scatting together and never once justify why they are doing this. Then again, Tony Bennett gots to get paid.
