"There Is Only So Much Oil In The Ground" is an ecologically-aware funker to kick off what was actually largely an album of soul/pop more than pure funk. However, this is the one more lengthy groove. The funk is still clearly here on the album, such as on this track, but just slightly less so than on the previous three outings. "It's Not The Crime", for example, is a short, two minute poppy workout, while "Come Back, Baby" is a Philadelphia-influenced soul number. Next up is a piece of sweet, laid-back brass-driven soul in "I Won't Leave Unless You Want Me To", a typical mid-seventies orchestrated soul ballad. One of only two really laid-back soul numbers on the album.
"Maybe It'll Rub Off" is in a kicking, lively funky vein and the funk continues with "(To Say The Least) You're The Most". It is notable that here is more poppy funk and less soul on this album than on the previous one. As I said, though, the funk is more to the point and poppier. That said, we get the sumptuous "Willing To Learn" which is once again very Harold Melvin-esque. Back to funk - "Give Me The Proof" is classic shuffling, staccato, horn-powered Tower Of Power funk, of the sort that influenced so many subsequent funk groups. "It Can Never Be The Same" is a soulful Al Green-style slow-tempo number and "I Believe In Myself" is another one with huge hints of Green about it.
