It's in A. The chords are A-F#m7-D-E (x2) then Bm7-C#m7-D-F#m7, Bm7-C#m7-D-E. The first progression sounds a bit like "Runaround Sue," but slower, and the second is a bit like the Byrds "Why?" but I wasn't consciously thinking of those when I assembled it. In addition to the cajon there is a bass, my Casino on rhythm, and a bit of synth.
Have fun!
