This is a great documentary by D.A. Pennebaker about Dylan's tour of England
in the mid-sixties. I don't think that it has ever been released in any
format other than VHS but don't quote me on that.
There is a great cd rom on Bob Dylan called HIGHWAY 61 which is a must. It
has a discography as well as song lyrics and Dylan database as well as
quicktime movies etc.
Hope this helps,
