White City Stadium was at the time considered the cutting edge of stadiums. To me its shape looks like a long hockey rink. They used the stadium until 1984 and demolished it in 1985.
The stadium was not used in 1948 when the games returned to London. Wembley Stadium had been built and was the main venue for those games.
White CIty Stadium was also the venue where Ray Davies of The Kinks- at the end of a concert flipped out, announced his retirement from the group and then collapsed of a drug overdose. He recovered and The Kinks continued on.
In 1974 at a David Cassidy concert- 650 were involved in a crash at the front of the stage, thirty were taken to a hospital and a 14 year old girl died of her injuries.
