Some various boring Jack Hammer info:
I've seen the LP a few times, worth around £40. there was one for buy-it-now on ebay for ages. The whole LP is nice Oscar Brown Jr style stuff, but 'down in the subway' the definite stand-out track, but also a nice track 'switchblade operator'. There's also 'love ladder' too which is fairly easy on 45 and not that interesting imo.
I also have a Polydor 45 which sounds like it's from the same sessions but has a great more northern style beat with his jive talk over the top & some nice solos, great dancer and real rare, it's called 'ode to a discotheque'.
I also have the Swedish 45 of 'down in the subway' and had a UK acetate of it which i sold when i got the Swedish issue, so it seems a UK release was considered.
'Swim' only got a 45 release apart from the Youngblood sampler, which has a different take of it. Bizarrely the backing track was used a few years later for a 45 by Mike Berry called 'dial my number' on the flip of 'tribute to Buddy Holly'! It's not bad too.
Safe to say i'm a Jack Hammer fan, he seemed to be a proper character & would love to hear his story. apparently performed with Elvis, recorded with Brigitte Bardot, was an ex pro boxer in the US army, I guess why most of his records are European releases as he was posted in Europe. In the late 50s he must have been big in Europe cos all his records got releases in most euro countries, mostly twist records.
The only 60s US release i've seen is credited to Jack E Hammer called 'cool swimming pool' and uses a Googie Rene backing track and is on New Bag. Sounds like him.
Best 45 i've heard from his early period is 'Twist in the morning' imo, which uses the 'Wade in the water' tune. again
er, sorry, i'm a Jack Hammer fan and cant resist the chance to go on about him. Found 'Swim' for 50p in the mid 90s and it rocked the club i was DJing in for years, so i feel i owe him!
