OK, granted, it’s a little more political than the post about the torch relay … but listen if you will:
Chumbawamba wrote a beautiful folk one.
Gil Scott-Heron wrote a jazz-fusion one (lyrics start at 0:56):
And, of course, UB40 wrote one or two reggae ones – this being the more well-known.
Interestingly, the lyrics talk of it being “five years”. For the record, it’s now been 38 years!

When it comes to Chumbawamba I like the old WW1 song they’re singing:
Chumbawamba have been going for many many years, and they never fail to move me.
A terrible injustice..
The first video I like it, lovely song about I am “Gary Tyler” I like his voice. Regards to @Alice
