well lets put it this way, theres as many English chimney sweeps going round singing a bit like Dick Van Dyke, as there are singing a bit like Martin Carthy.

and a lot more people know the songs from Mary Poppins and Chitty Chitty Bang Bang than are acquainted with the classic works of our great folk revival.

why theres only one word for the man,,,supercalifragilistic etc!

I might write him a song

Dick van Dyke
I really like
in fact he is an icon
he strong and stable, just the chap
for you to lean your bike on
