Wasn’t doing a geographical list, but as it turns out I don’t know any of those groups/songs...tx. Actually, I know a Chanters groups (No, No, No), but they’re from Queens, NY
I’m familiar with the Chanters from Queens. The group of the same name on the Combo label is from Watts, a neighborhood in southeast Los Angeles, as are Donald Woods & the Vel-Aires. “The Man from Utopia” is said to have been inspired by Utopia Cleaners, a dry cleaning service on East 98th. Street in Watts. Last time I drove by there, the business was gone but the building was still standing.
“Tell Me” by the Gassers was recorded at Dolphin’s of Hollywood, a record store at Vernon and Central in LA. There was a studio in the back and a radio station in the front. You could record a song in the back, bring it out front to be played over the air, and if the listeners liked it, you’d have an instant hit.
