Penny in a Hat by Jessica Harper
As this song is not available on iTunes or for listening anywhere else on the Internet, 
are the chords for the little 30 second sample I could listen to.
Any other verses follow a similar pattern and the same chords (if I remember correctly)

D
Put a penny in the old mans hat
G
Kiss your mamma?s hand
D
Wipe the baby?s tears away
G
Give what you can, Give what you can
D
Find someone who?s feeling blue
G
Sing them a sweet refrain
D
Take you sister show her how to
G
Brighten rainy days
