Here’s a song called “Looking for an Echo,” written by Richard Reicheg that was first recorded in 1975. The Persuasions put their own spin on it, adapting it to their own history as an a cappella group that formed in Brooklyn in the 1960s. They did a lovely version of it on Spike Lee’s seminal 1990 concert film Do It A Cappella, but I can’t find just this song on the Tube of You (though you can see the whole film — click here to start at “Looking for an Echo”). Here’s their lovely studio recording of it.
