My friend Mark Moring just sent this in:
At the age of 11, Keith Green appeared on the TV show I’ve Got a Secret, hosted by Steve Allen, in 1965. This is before his conversion to Christ, but in the song he plays near the end of the segment, his style is already evident. Pretty cool stuff:
Oh wow. Keith Green. That brings back memories. I used to have all of his recordings and was crushed when he was killed.
You’re right, his style is evident during his song. Thanks for posting.
