Well, its quite posssible that Orpheus had more than one friend whose music we have listened. If its organist, I think I know who he is and I am not sure if its polite for me to say? Anyway, this guy played with him ( with that organist) on one album and than got the chance to record his own album as a leader, made two, but did not became famous. Here is the link...Fred Jackson 'Hootin and Tootin'...
