Thread creep alert. In one of the "related threads" linked above, somebody named Dave Potts in December 2000 quoted a parody of this song that was used by Philadelphia's WXPN-FM as a promo:

Some folks D-R-I-V-E to the D-I-S-C-O,
But me I stay H-O-M-E by my R-A-D-I-O.
I don't take D-R-U-G-S, not even aspirin,
I get my H-I-G-H-S from W-X-P-N

I remember that one now! It was around 1969. I used to listen to WXPN and WMMR, Philly's "underground" radio stations (XPN was definitely farther under), from about 1968 to 1970, when I left Philly for Princeton.

WMMR also did a series of promos like this, with a Neil Young soundalike:

Oh, to listen to WMMR
It's the hippest radio station in the world
You won't hear garbage on WMMR
(Uh, well, I remembered some of it)

Another one went:

Hello out there in radioland
This here's your old friend Neil Young
After all these station ID's
I know you're thinking it's not really me
But if it was, now, you know for sure
I'd listen to WMMR
In Philadelphia, in my home or in my car...[guitar riff]

OK, enough of that. There's another thread on this topic, which did not show up when I searched before starting this one, which does have the source for the OAT version. But it doesn't give any more info on the Coffeehouse Songbook version.

By the way, there's another Philadelphia connection here: the photo on the cover of the original Coffeehouse Songbook is of the interior of The Main Point in Bryn Mawr, Pennsylvania, on Philadelphia's Main Line. I spent many a wonderful evening there in the early 70's.

Aloha,
