It was first mentioned here on page 67 by Deius Infectus (
post 995; the song was ID'ed and lyrics written out in posts 992/1005.). The original homework on both spectrograph and covering song was done on the then-official TINP forums, sadly now (apparently) lost to time.
To be fair, the only reason I was able to pull up as much info today as I did was because I took three hours last night and reread this whole thread. I've been going to the current Madge page for several months now and completely missed that the song we've got now is the same one that appeared back in 2006.
