Here’s legendary crooner Tony Bennett having fun with Lady Gaga, performing a duet of The Lady Is A Tramp, a classic show tune from the 1937 Rodgers and Hart musical Babes In Arms. The track is featured on Tony’s latest release, Tony Bennett: Duets II. He still sounds great at age 85, and this is such a perfect song for Gaga (we all know she loves musicals and being theatrical), watch the music video below!
