Mine was Money - Barrett Strong on London honest, about '61. I was the only Soul (or whatever it was called then) Boy in the village (actually it was R&R & R&B stuff like the Drifters Phil Phillips etc)) and someone I got talking to in a record shop told me he knew of someone who had a few strange records he wanted to sell. I got in touch and bought about 10 things off him Money, Don Gardner & D D Ford - I Need Your Love, The Falcons - I Found A Love, James Brown on Parlophone and a few others. God knows where he heard them. I'd never heard of any of these myself until then and it confirmed for me what I wanted to seek out in future. Re; Radio Luxemburg. They did occasionally play obscure stuff but I remember listening to the Oriole show for weeks to hear Motown stuff with no success and it was often true of other programmes. The best way then to home in on soul was to buy the Record Mirror and read the reviews. If there were strange names like Solomon Burke or Jnr Walker you knew they'd be good! And the Norman Joplin column in particular was a great guide.
