Yes speedway took place at all 3 meetings - I've copied below the main info from the ebay adverts -
On offer is a programme for the Daily Mirror Cavalcade of Speed held at White City Stadium on 30th May 1956. The programme measures about 5.5 inches by 8 inches and contains 32 printed pages of adverts and info on the nights events which included The Royal Artillery Band, 7 a side Rugby (Harlequins v Cliff Morgans team), Athletics, Polo, Showjumping, 6 a side Football (Manchester City v London All stars), Speedway Racing, Greyhound Racing and a fireworks display by Brocks Fireworks. The centre of the programme has a timetable of events with spaces for the winners to be written in and this has been done neatly in ink pen. There is a page long article on each sport. The adverts range from Babycham to Lucozade and many more. A nice piece of nostalgia for the collector.
