I have a feeling Curtis never heard of either 45. Triad was based in El Cerrito, California and besides KSOL (San Francisco) playing "The Soul P.W.', I can't find it getting airplay anywhere and it didn't get reviewed in any of the trade papers. The Jessie James 45 was a flop- no mention in the trades and no signs of airplay.
On the other hand, it's possible he knew of both and had them pulled off the market.
