Neat thread, Allan. I sang "Katy Dear" at the Getaway and got a number of blank looks. One of my favorites and a lot easier for me to manage than "Silver Dagger" ala Joan Baez. Somehow I know it as:

Katy Dear, go tell your father
If you can be a bride of mine

and a few other minor differences. I will have to dig out my Ian and Sylvia CDs and check.
