So glad someone found this! I was falling asleep in front of the TV several weeks ago and woke up to one of those Time-Life infomercials. Still half asleep, I swore I saw someone singing in front of a TR3, but I seem to recall at that moment it was only background video while the announcer was babbling on about all the songs in the collection.
I wonder what show this was taken from, and whether Triumph might have been a sponsor, or ????
