Thank-you all: Unfortunately - due to 'brain damage' fingers don't move fast enough to hit an 'F' with any degree of accuracy (it's one of the 'common' chords that still eludes me!) so I'll transpose it up one!
Only bugger doing it that way is that the Am (which sounds great) becomes a 'simplified' Bm and sounds less so - but I can put up with that if I can play the song!

Cheers all; and again - Thanks
