I probably go back further than the rest (or most) of you, but can anyone tell me about this "gas tar bubbles?".....also, earache was a common problem in the 50's/60's and what was the stuff my mother used to warm up by the fire, put on cotton wool and shove into my ears? I hated it as you could hear the crackling as it broke up the ear wax!!!
