I found one that I think is rather rare. In the car I always listen to the 50's channel on my Sirius radio. That channel usually plays the standard Doo Wop songs; however, a few times a week, there is a program that features rather rare, unknown Doo Wop songs, and I heard one called Look For An Echo. There is lots of nostalgia in the lyrics. I found an Australian group did it in Australia, and other have also performed it.
