For the verse:
            G                      Bm        C
She's a jar with a heavy lid, my pop kid quiz....
(it keeps that pattern the entire way through)
for the chorus:
G              Am             Bm                          B7
Just climb aboard, the tracks of the trains are
Em                                    Bm      Bm-Bbm-Am
Through my fragile family tree

Am                                   F#dim
watch me floating inches above the people underneath.
