Frankie Lymon and the Teenagers were a force to be reckoned with during the fifties. They were professional and had a few Top 40 hits in the doo-wop style. I'm going to embed one of their videos in this post.
Of lesser fame was Frankie's little brother, Lewis. His group was called Lewis Lymon and the Teenchords. (Very similar names, and probably intentional.) The video above is Lewis and his group.
Now here's Frankie doing a real kicker. What a voice and what confidence he had! Enjoy!
