This one is going to require some patience kids. First off, we have a very unique situation here, where the same artist took three (actually four) different swings at this particular ball. Then there is a matter of length... this is a long ass song. But couple that with a disco version? And you know it's going be a matter of time and patience. Fortunately, we are mostly dealing with edited versions, trimmed to fit the 45 format.
But, I think it's worth it. I adore these two performers and I adore this song. And the song's history is a rather interesting one.
