There's a bent note in the harmonica solo (it contains both F# and F natural), which is a technique way beyond my harmonica playing ability, so I used melodica, which is much easier to play and doesn't sound too drastically different:
After I recorded these two parts, I realized something about the song: the phrase "Like to get your feet up" ascends (spanning a whole octave: D E F# G A D'), musically giving a picture of that "get[ting] your feet up."
