Ramblin' Jack did my favourite version of Don't Think Twice.

His first LP had Ian & Sylvia and John Herald guesting with no liner credits. Shel Silverstein wrote the liner notes which are worth the price of the LP.

I love the recordings of Ramblin' Jack, but the worst live performance I've ever seen was by Ramblin' Jack at the Freetimes Cafe in Toronto. Jack was drunk and forgetting the words and "rambling" on and on about nonsense.
I still love those records and they still spend a lotta time on the turntable.
