Sounds like the smart thing is to put one copy in, and see what happens. Maybe Ferrara will come along and post a review-- she got a gift set awhile back. I mean, she got one set of the Green book arrangements that were extant at the time.
I thought I would wait to put any of this in, till the LP rush slows down a tad.
Maybe tomorrow I will post the TOCs of the other volumes.
Oh, and I should mention-- quite a few of the songs in all volumes have additional verses I added. As to whether my ghostwriting attempts are any good, at least one of them has gone into a Mel Bay anthology-- at least I think it did; I have not seen the book itself yet, but I was asked for permission to include my version of the song.
So, I guess that makes this a one-of-a-kind resource of eclectic gospal styles and time periods.
