Saw the news that Sammy Campbell from the Del-Larks just passed away, so I was searching for more stuff to read about them when I found this great paper/article.
Doo Wop and Soul in the Birthplace of Funk: The Story of Sammy & the Del Larks (2.9 MB)
Besides the info on the Del-Larks, it also includes a lot about the Parliaments and when Ray Davis was a part of the Del-Larks. Great stuff. So if you wanna get your feet wet in Plainfield doo-wop, you should check it out!
It’s written by Charlie and Pamela Horner over at classicurbanharmony.net. They have a lot of doo-wop stuff on their page. Talked with Pamela about posting it here. 
Here’s an image of the Del-Larks (with Ray Davis in the middle).
