Bramble on

Leaves are fallin' all around, time I was on my way
Thanks to you, I'm much obliged for such a pleasant stay
but now it's time for me to go, the autumn moon lights my way
for now I smell the rain, and with it, pain
and it's headed my way
Aw, sometimes I grow so tired
but I know I've got one thing I got to do

A-ramble on, and now's the time, the time is now
