I am not familiar with the singer June Valli, she isn't related to Frankie Valli, but she recorded a real gem of a song titled "Apple Green", it was a Billboard hit in 1960, reaching the #29 spot. I found a video on You Tube where she performs the song, it's from the June 4th, 1960 airing of Jubilee USA on the ABC network. Watch and enjoy, such a pretty song.

I found the complete episode, including the commercials, of the June 4th 1960 airing of Jubilee USA on the ABC network. At the 17:30 mark is when June Valli is introduced, and then she performs "Apple Green".
