two mid 70's songs

[ernesto]

Can anybody tell me who performed a hit soul song around 1975 that said "push together, push together...".
Also: anybody know about an purely instrumental piano song that was no big hit but was played on the radio and discos around 1976 and sounded a lot like Love Unlimited Orchestra. So much sounded like Love Unlimited that I could say it is from them, but does not appear on "The Best Of Love Unlimited Orchestra" from the "Funk Essentials" label. Any tip?

For the instrumental track, try either "Spring Rain" by Silvetti or "Surprise" by André Gagnon.
