The Essex St. Journal were from Walpole, Massachusetts, a suburb of Boston but but this one 45 on the Planet label out of Providence, Rhode Island.
The A-side “Walk On” showcases a bleary vocal matched with the guitarist’s wah wah; it’s never been comped. I prefer the flip, “Progression 256” an adaption of “Money” with plenty of excellent sustained and occasionally out-of-tune lead guitar (not a bad thing in this case).
Both songs are by David Rediker and Dave Norton and published by Ramford Music (sic – I believe the company’s true name was Ranford Music).
I’ve read this is from 1967, but I’d say they recorded this in 1968, after many listens to Disraeli Gears and Wheels of Fire.
According to Barry Parquette in a comment below, other members included his brother Mark Parquette on lead guitar.
