Deeper grave, construction workers with a vacuum excavator.Also, I wasn't aware we had this thread.
The tape hasn't aged well either, despite boasting Dolby B NR on it it sounds awful with it on or off, I guess years in my cheap players since I got it in 98 (first heard it in my uncle's Pug 306 [the first time I ever experienced automatic wipers], on the way to see the filming of Robot Wars in that year so must've got the cassette soon after) have done it no good. Other cassettes sound much better.
I'll just listen to it on Spotify and try the deck when I can find my missing 2 Unlimited or Flat Eric cassettes. The cases are there but empty!
