Songs written by people you never realised
How many times have you heard a song that you thought, hold on, how is he/she singing that, that was twenty years before it was writtent by xxx
Example, today on last fm I was treated to "Always on my mind" being sung by johnny Cash and Willie Nelson. I thought hold on, the pet shop boys didn't do this until the 80's or something. So I done some digging on wikipedia and found out it was written by three country music guys and has since been covered by over 300 artists.
Other songs that spring to mind are
Knockin on heavens door - Written by Bob Dylan(Still my favourite version) and covered by Eric Clapton, Guns and Roses and many more.
Anyone got any other good ones?
