^prob billymac's sweetest falsetto is on the b side of the 'take me to the girl' 12". the title song versioned in tinkling small hours jazzclub style and renamed 'the girl that took me'
perfect poise, delicious phrasing, and testament to all the couldabeens of a wasted talent.
but hell i also love the much maligned 'perhaps' which despite being marred by terrible prod' is full of brilliant songs inc single 'those first impressions' which is cheeky, slinkily sexy and cute as hell, and also features his v controlled and finely spun falsetto singing.
beach boys again...
or, more precisely brian wilson's falsetto, one of the 7 wonders surely!
two off the top of my head:
'the warmth of the sun' - ouch!
...or the version 'surf's up' with just him at the piano that you can get on various smile boots or box sets
look in bluegrass for lots of great falsettoes
bill monroe of course for starters
'the high and lonesome' they called it...
