Before the screw-top bottles, Corona used to have digit-snapping metal tops which required the use of both thumbs to open them. Tizer, though, had screw-tops with a rubber seal. Nostalgia ain't what it used to be.
Early seventies in north London, we used to get the Corona van on a weekly basis.
As an aside I won a case of pop off of them when I was a very small child.
It was a fancy dress competition at Butlins and my mum dressed me up in carrier and paper bags, and called me "Bags of fun".
I am still in therapy to this day, and every time I think about it I get a shudder down my spine.
There is a photo somewhere and if my doctor gives me permission I will post it.
I came second.
