A medley of versions of "this tune" would last for a whole night's performance.And, just to round things off. . . Any Oz catters from "Jack the Lad" out there. It was there version of Bachgen Bach that started my partner thinking about the association with Lachlan Tigers (way back in December 1996 in Woodford Queensland Australia).
I began asking catters about it, and associated tunes around 8 months ago.
Keep looking all. This is fascinating.
