I've just watched for the first time in 30 years footage of the series between Australia and England in 1974/75. The tapes have approximately an hour of highlights from all 6 tests.
Even though England lost 4-1 it is still great to see such historic footage. At the time in England all the coverage we had was 25 minutes of highlights late in the evening and two hours of live crackly radio in the early hours of the morning.
I'm hoping that somewhere out there is footage available of the following winters (Australian summer) series between Australia and the West Indies which Australia won 5-1.
