Dan, I assume you also know about the Scorpions "Wind of change" which was #1 back in the 80s/early-90s (can't remember exactly).

Geoff, the other "Power of love" is the Frankie Goes to Hollywood one.

Steve Knightley wrote "Widecombe Fair" as an alternative take on the traditional Uncle-Tom-Cobbley-and-all version with the same name.

There are several songs called "Fire in my soul", one of which is the Davey Graham version of "Nobody's fault but mine" where he misheard "If I don't read it (and) my soul be lost" as "Fire in my soul oh Lord".

And I'll raise you different songs with the same name by the *same author*. Chris Rea wrote two completely different songs, both called "Texas". (Neither was very good, BTW.) And Leonard Cohen did two very different versions of "Chelsea Hotel" and "Hallelujah".

Graham.
