The Hollies "Sorry Susanne" - Brian & Al unison; the BBs back-up.
Sam Cooke "Only Sixteen" - Bruce. Brian with Wrecking Crew backing track.
Screamin' Jay Hawkins "I Put Spell on You" - Mike revising "Monster Mash" shouts & crazy laughters. With little help from Brian.
Pink Floyd "Hey You" - Mike/ Brian; Al "But it was only fantasy"; Carl "Hey you! Don't tell me". David cool guitar jamming.
Lou Christie "Lightnin' Strikes" - Dennis; Brian falsetto; The Honeys back-up.
Hey You would be very interesting indeed. I wonder if Brian would lighten up the arrangement at all, being it's part of Roger Waters' dark masterpiece The Wall. The Wall does however feature Bruce Johnston on backing vocals, and allegedly Carl also. I think the full group was going to appear as Roger wanted Beach Boys style vocals on some of the tracks, but they declined as the content of the album didn't exactly jibe with their sunny music (The Beach Boys were in full nostalgia mode by this time).
