Thank you. It's one of the Tones Hi-Fi Songbook items (there were 80 at last count!) with which I won't bore you, except with my favourite Upgrading Song:
Dough for gear, that’s really dear
’Ray! From better up to best!
Me, for me, ‘cos I can hear
Far, far better than the rest
So, why needled, filled with dread?
La-tterly heard better, so
Tee-tering on new upgrade
Which shall bring us back to dough-oh-oh-oh
Another reason I hated the Wam. Juvenile, pathetic nonsense. Not clever or funny.
