Weren't these very popular with the rockabilly crowd? Weren't they also a poly/cotton mix? Didn't they sometimes have 'Sam's Garage' on the back or something of that nature? Definitely not 'Ivy'; not, I should imagine, in any Ivy Shop/JS sense.
Yes to lots of that. I was in London a few years ago and had a night on my own so went to the bowling alley under the hotel on Southampton Row as there was decent music being played. When I got there on a midweek night it was a full on 50s thing as the alley is maintained from that era. Everyone was in Rockabilly gear, enjoying the music and some food. Lots of bowling shirts as you might envisage. It was an unexpectedly fun few hours.
A couple of us edged towards the rockabilly crowd in 1979. They were often in heavy woollen jackets and clumpy boots and danced by themselves while the Bill Haley types jeered. Then there was all that 'South's Gonna Rise Again' stuff - that you still around Cotmanhay, Mark. Anyway, that was over forty years ago. I used to talk to a jukebox fanatic in R.E. Cords in 1976/77, who was fine with the punk rock thing. Most of the old rockers were deeply hostile. Derby was primitive. Still is.
A few of my mates started to wear bowling shirts (and baggy pleated trousers with dodgy shoes) in the late 70s. When we got cars we started to go to clubs in the wilds of Essex. I stuck with BD shirts and even got some of their cast off old BD shirts. No rockabilly music played at the clubs though.
