The Freddie factor will help give Yorkshire their biggest crowd in nearly 15 years for today's Twenty20 showdown with old enemy Lancashire.
Andrew Flintoff, who will captain England in this winter's Ashes series in Australia, continues his return from a long-standing ankle injury with his second Twenty20 encounter in 48 hours following an impressive three for four return in Lancashire's seven-wicket win over Nottinghamshire on Sunday.
And his presence in the Red Rose line-up will take the Headingley Carnegie crowd up to its limit of just over 15,000.
Yorkshire chief executive Stewart Regan said: "A small number of remaining tickets went on sale at 9am and we're looking at selling out. It's our biggest attendance since the early 1990s and we're obviously delighted at the interest the match has generated."
Both Yorkshire and Lancashire still have a chance of qualifying for the quarter-final of the competition as one of the two best third-placed clubs in the three divisions.
The Tykes are drinking at the last chance saloon following yesterday's wash-out against Derbyshire which brought them only one point after they had raced to 210-3.
Victory tonight will mean they still have a chance of qualification but they will be watching results from elsewhere.
For Yorkshire to take their place in the last eight they would ideally need Warwickshire and Glamorgan to lose their respective games at Worcestershire and Somerset. Even then, the Tykes' qualification may depend on run rate.
