Wineterwatch 1963 - the Big Freeze

The winter of 1962-3 was one of the coldest on record in the UK with
persistent northerly and easterly winds bringing heavy snow as lakes and
rivers froze over.
Chris Packham introduces this archive documentary, originally shown in
February 1963, and asks how wildlife would cope with the same conditions
now.
