I've just found an old 1930's valve radio in the garage and it brought back some memories for me of my childhood listening to the radio with a mug of cocoa in my hand just before bedtime.
The Clitheroe kid, Educating Archie, The Billy Cotton Band-show, Journey into Space, The Goon Show and Two-way Family Favourites on a Sunday lunchtime and Radio Luxembourg and later...Radio Caroline.
What do you remember from those radio days ?
