"The love of a good story" is right Jim. Bert certainly had it as well.

I remember the first time I heard Bert sing Tam Lin was at the Cellar CSH (probably from memory 1967 or 8. I'd taken a lady friend who wasn't particularly into the music but enjoyed the evening. On the way home I commented on what a great song Tam Lin was, when she asked which one that was and I'd described it she added that she hadn't realised it was a song and thought he was telling a story. Which is a great comment on Bert's communication I think.
