An article Mike Markesich wrote and was posted on RSF sometime ago. Sure I've seen a photo of them too
"Detroit Soul on Music Town" from Mike Markesich
Well, first off, the Detroit Soul were from New Britain, Connecticut. And
they were all high school kids! The group used some members of their high
school marching band on the recording of "All Of My Life". That single was
released around September 1967 and was a Top Ten record on the Hartford, CT
radio scene. Here in the New Haven, CT area (which is right on the CT
shoreline, it made it up to #31 on the weekly Top 60 radio chart. One of the
members died in Vietnam...I don't think it was the lead singer, Sal Lenares-
-he was in an earlier group called the Soobes, who might have recorded a
track on the CT various artist Soul sound LP's on the Fling-O label. I have
never seen the LP, so I can't say for certain.
Anyway, getting back to the group, I used to work with a guy who went to
school with the members of Detroit Soul, and he said they could pull off
soul as well as chart hits of the day. Their second single, "Does Your Mind
Go Wild" came out around May 1968, and was nowhere near as popular as
"AOML". Sal was out of the group by that time, I think Bill Durso, lead
guitarist is giving his all on lead vocal. I like this disc too, wish they
could've employed a black female chorus to coo the title instead of some
local white girls.
