Original studio version recorded in the key of Gm. (in which Lindsey has been quoted as saying almost from the moment the album was released that he should've re-recorded it in a lower key)
Live versions from '75 up through
The Dance played in the key of Fm.
Not sure, but I could've sworn that on the 2003 tour & later he's played it in Em.
So it's evolving into lower keys AND getting played slower & slower & slower each tour. Pretty soon it'll get so low & slow that he'll switch from guitar to bass to do the solo.
