Here's one of those gospel 45s I promised a while back, "Two Wings" by The World Wonders on the Cherub label outta Chicago. It's a very nice mid-tempo tune featuring some great group vocals.
It opens with an organ and guitar over the drums, and then the group vocals come in, and the harmonies just take you away. When the lead comes in for the opening chorus, it's almost an angelic voice, similar to Sam Cooke almost. The group then take turns singing verses, and it's a nice range of delivery styles, and that's what this song is all about. The band never strays very far from it's rhythm, just some guitar flourishes here and there, a subtle change in the tempo, allowing the voices to be the focus. Very nice.
