I reckon the original comes in at about 132bpm (it doesn't actually keep a steady tempo - it drifts a bit...).
I use a clever piece of inexpensive software called, improbably, 'The Amazing Slow-Downer', which does a very good job of rendering the track a very acceptable foxtrot at 91% of original speed, without any change to pitch, and without doing violence to the vocal quality of the singers' voices.
I find it very useful to tweak all sorts of music that is 'nearly' but not quite at the right speed for dancing. +/- 10% is usually fine, and you can go further with instrumental music.
It is very useful as a teaching aid, because I can slow down tracks, for teaching & practise, without making sopranos into tenors, and it was money very well spent.
