I wanted to hear how it would sound over a swing beat, so I made my own a capella (plus iPad Mellotron XL) version really quickly yesterday in Audition. Two takes, one for loop and lead vocal, then a second pass for harmonies and fingersnaps. Really quick mixdown/nip tuck for timing and... done. Listened back today, and though it's still not quite in time, I forgot some of the words, and my voice goes flat in places, I'm surprised it turned out as well as it did.
