Wilco - Shes A Jar Ukulele

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.
