I listened to the linked track on the record and could not detect any of the Beach Boys' members in the background couldn't even find Brian Wilson in the background.
I looked in detail at the back cover image seen and saw that the background vocalists listed were Nigel Olsson, Dee Murray, Tom Bahler, Jim Haas, Linda Carey Dillard and Laura Creamer. NONE of them were members of the Beach Boys, which is the first thing disproves the Lemongello family statement that they played on this album's sessions.
The second thing that disproves that statement is a clip I found of a live performance given that year by the Beach Boys of their 1965 hit "Good Vibrations". They had tenor-to-baritone harmonies, whereas the background singers listed had soprano-to-tenor harmonies.
Do I Love You: The Beach Boys sang background and one listen to this will tell you that it’s obviously them! Nobody has a sound like The Beach Boys. They have one of the most distinct and recognizable sounds on record. I’ll let anyone who wants to judge for themselves, once you hear this, you’ll know instantly it’s them.
ReviewAfter selling roughly 43,000 copies of his self produced debut LP via television advertisements in the New York area, Lemongello signed to Private Stock Records. In late 1976, this album was issued. While it does have it's shining moments (the title track, A1, A4 and A5 being those that stand out), overall this is a very bland album. The other tracks on the album just kind of fall flat and aren't at all memorable. After this album's failure to chart, he was dropped from Private Stock.
This album and all of the singles from it all failed to chart on Billboard and Cashbox. Peter Lemongello claims the Beach Boys sang backup vocals on it. No former or (then) current members are listed on the LP's back cover, and if you listen to the album, it doesn't sound at all like their harmonies.
