This is a few months old but I thought I'd mention it anyway.  Back in 2003 funkin.com reported that Jamiroquai had broken the capacity record for Wembley Arena in London.  Well, in June of this year Jamiroquai's record was broken by Pearl Jam.  Music Week (UK) reported...

"With 12,470 Pearl Jam fans packing the venue in North West London yesterday, compared to the 11,673 who attended their last sell-out gig at the arena in 2000, the band set a new house record. The previous house record of 12,337 was held by Jamiroquai for their 2002 show."

Wembley Arena was closed and re-developed a few years ago and as such Jamiroquai still retain the capacity record for the old venue.
