I am not sure what the record they are going for is ...
"One hundred pinball machines will fill the main lobby of First Canadian Place (100 King St downtown Toronto) on Thursday, May 16, for a special promotion of the Festival’s 2013 production of Tommy. Join us between 9 a.m. and 6 p.m. for a free game, as well as performances by members of the cast at 12:15 and 1:15 at the Waterfall Stage.
The Festival is aiming to enter the Guinness Book of World Records with this event – so come out, have fun, and help make history!"
