And also, there are a few examples of groups that have not been found or verified as being from the same locale / state as their record label:
The Wave-Riders on Tener - possibly a Washington, DC area group, still unverified;
The Monarchs (3 45s on Bruno), possibly a college group comprised of members from different states, songwriter came from Maryland;
The Gnomes (Afton label) might still be the longest 'known' sought-after garage 45 that has foiled all attempts to track down. I did come across a newspaper article but it had no names of the group members.
