Why do I like it? Because it has an unusual and interesting structure. It uses familiar chords but in a refreshing way And it has a good melody.
It is a tune of 24 bars - an unusual length for a song chorus. The first 16 are 'standard' and give the feeling that they will lead into a similar second sixteen. They even end, typically, with the chords II7 | II7 | V7 | V7. But then, instead of going into a further 16 bars, the tune is rounded off with just 8 bars, of which the last four reprise the first four of the tune. I make no claim for 100 accuracy with my version, but I have done my best. I have put it into the key of C to suit my own playing:
I like the 4-bar memorable theme that occurs in Bars 1- 4, 5-8 and again at 21-24. I like the climb up through the arpeggio of II7 (D7 in my example) that occurs in Bars 13-14.
Georgia White recorded the song in Bb:
Erika Lewis of Tuba Skinny took it down to G to suit her voice:
