David Simon , who I graduated from Mineola ( Long Island ) HS with in 1959 , was indeed
The Legendary Bruno Wolf in the Jim Kweskin Jug Band. I was in touch with him throughout his life. He passed several years ago in NJ where he lived with his sons . He turned out to be a very good harmonica player. His main direction ( aside from music ) was health food and nutritional supplement marketing. He was involved with Scientology but didn't practice it.
