This song reeks of success, and just about everybody involved in it went on to a smash career. The song itself is almost an institution - it's a contender for one of the top most-covered songs of all time. Cover versions include artists Andy Williams, Engelbert Humperdinck, Diana Ross & the Supremes, The Temptations, Julio Iglesias, Gloria Gaynor, Maureen McGovern, Manic Street Preachers, and Lauryn Hill (who got a Grammy nomination - Best Female Pop Vocal Performance - for her version).
In our interview with Frankie Valli
, he said: "It's a very, very tough song to do badly. When the song is that strong to start off with, that's the kind of song you look for. I mean, if I were to do an album of songs that I wish I would have recorded, I certainly would have looked for those big ones. I wouldn't be looking for obscure ones, I'd be looking for ones that people have success with."
