She Caught the Katy and Left Me the Mule to Ride...

She Caught the Katy and Left Me the Mule to Ride is a song written by Taj Mahal and James Rachell on Taj's 1968 album "Natch'll Blues." It probably means that the woman he sings of jumped on the Kansas Texas Railroad and took off and all he was left with to follow on was a slower "mule" or local train.

With the advent of most Americans traveling in cars as big as buses trains are not as much in use and while I have taken trains most people around here don't travel that way. 

We do have mules. And Cows. And grandkids.
