The JFK shows in Philly were around 90,000 each
150,000 at Roundhay Park, leeds on 25th July 1982
theres no accurate figure for Rio, Hyde Park and Altamont as all were free shows, although Hyde Park was probably around 250-300,000 with Altamont possibly being in excess of 400,000
Knebworth was around 200,000 I think, so the top 5 in order are probably
1) Rio 2) and 3) Toronto or Altamont 4) Hyde Park 5) Knebworth
This site by Jens Backlund makes interesting reading if you';re into those type of statistics, although it hasnt been updated since 2001
