Eldest Daughter has been foraging amongst my old cassette tapes and vinyl records. She found a Steve Green tape and promptly went on-line to find digital versions of his music. She found the performance below of "God and God Alone"--which sounds just like the tape version. She has, of course, researched what Steve is up to now, and she says that he doesn't try to hit as many high notes but is still singing well. She also informs me that for an awful period later on he did sport a mullet but mercifully not for very long.
It's hard to believe he was only about thirty when he recorded this. He has a wonderfully mature voice, while looking incredibly young.
