70's as well.
I turned 20 in 1976.
Hated disco.
Was into Hawkwind mainly, read a lot of science fiction which tied in well with Mike Moorcock's involvement with Hawkwind. I was quite into his eternal champion concept, Elric, Hawkmoon etc. Plus they had an eternal companion too, in some forums my user name is Oladahn after Hawkmoon's companion.
As I've mentioned elsewhere I had a rather lonely time as far as female companionship, being hit upside the head with an ugly stick didn't help. But I had a great, small bunch of friends and we got up to all sorts of mischief together. Did a lot of fishing and rabbiting with them and my dad. Fiddled with cars and motorbikes, Went through several years of technical training college (electronics).
And despite my lack of success with girls I still look back on this period with a great deal of fondness.
