``This concert is happening to honor brave guys like these, so when Heather (Mills, McCartney's fiancee) told me they didn't have tickets I thought, 'Well, we've just got to fix that, haven't we.'''
Accordingly, McCartney dropped in on ladder company 55 on Broome Street and ladder company six on Canal Street, both of which sit within blocks from the smoldering ruins of the World Trade Center where some 5,000 people were killed in the Sept. 11 attacks by hijacked jetliners.
McCartney surprised the firemen, who his publicist Geoff Baker said were ``sitting and talking, having coffee,'' handing out 100 $2,000 tickets to the concert.
