I’m my own Grandpa

As a great Grandfather I love this song so was really pleased to Chordify the 1947 Lonzo and Oscar version. Its neither terrifying nor easy requires a bit of thought for the strum pattern, however imagine this I am learning module 10 and got sidetracked into playing this and when I finished I could still here it, I didn’t understand but freaky it was playing on the radio in the kitchen, Really what are the odds it’s hardly a popular song today.
