I was watching a 1982 replay of Top of the Pops and they showed this How many reel to reels did Philip Lynott need ? At 0:43 he switches to a very chunky cassette player. The miniature TV would have been the height of technology back then. p.s I forgot to say that this was the theme tune of Top of the Pops back then so should stir a memory in any UK readers over the age of about 40.
I watch Top of the Pops every Friday on BBC Four, it's really interesting to hear all of the 80s music I like from when it had just been released.
