Tony Bennett and Lady Gaga certainly appeared like the oddest of couples.That was most definitely the case when the “I Left My Heart in San Francisco” crooner paired up with the shock diva — who sang “He ate my heart” on 2009’s “Monster” — for their first collaborative album, 2014’s “Cheek to Cheek.”The two had previously worked together, on his 2011 “Duets II” LP, playfully partnering on “The Lady Is a Tramp,” the same year that Mother Monster had gone full-on zombie in her “Born This Way” video.That was about as far as you could get from Bennett’s classy, debonair style.
