Need tickets to see Sir Paul McCartney at Fenway Park Tuesday? You may be in luck. Live Nation announced that a limited number of additional tickets have been released and are on sale now through the Red Sox ticket office, LiveNation.com, the Orpheum Theatre box office at 1 Hamilton Place, or by calling 800-514-3849. They might be gone already — but you won’t know if you don’t try. The new seats were priced at $74.50, $104.50, and $255 (plus taxes and fees, of course). McCartney kicked off his current tour in June when he headlined the Bonnaroo Music Festival in Tennessee.
