There were some copies floating around on alt.binaries.sounds.mp3.1960s
If you're familiar with usenet, and have a newsreader like Agent, you might want to see if someone would post a copy. I know of no place to get a copy of the show unless you're buying it for broadcast.
The copy that I heard on Usenet was the History of Rock & Roll, but I don't think it's the version that most people want. If anyone from Drake Chenault or "in the know" can clarify, please do. I'm still unclear on the chronology of the show and can't confirm the story below.
I, and a few other guys, were comparing notes on the History of Rock & Roll show and have determined that there were at least three "versions" of the program.
I ended up tracking down a guy who worked for Bill Drake, and he clarified the show in an e-mail. Here is what he said;
Three longform versions of the H.R.R. were produced. The first was the 1969 KHJ version, with narration by Humble Harve. The second was the award winner, the 1978 version which Bill Drake narrated and I wrote and co-produced. One easy way to tell if what you have is the 1978 version is to play the end of the timesweep in Hour 52. If the last song heard in the montage is "You Light Up My Life," it is the 1978 version.
I would love to find the second version myself.
The third version is what I think I heard in the newsgroup, but the poster put it up in mono, 48 khz, and it sounded bad even on an Ipod with ear buds. I think I had it for about 2 days then erased the files.
Check on usenet. Someone has to have a good copy .... somewhere.
