Here is an old tune that should be good practice for beginner and intermediate pickers. (33) Harry S. Miller – The Cat Came Back – YouTube. This version fits the riff that Thomas describes in his recent post.
Another version by Cisco Huston (33) Cisco Houston – “The Cat Came Back” – YouTube has the melody I remember .
How many ways can we play the cat came back? If you have a favorite version post the link in the comments. We do the usual song circle when were done with the cat.
