DERBY LINE, Vt. (AP) – A play scheduled for this weekend at the Haskell Opera House had to be rescheduled because of the traffic jam caused by the Phish festival in Coventry.

“A Funny Thing Happened on the Way to the Forum” at the Haskell Opera House will now run next week, starting Thursday, instead, said producer Lynn Leimer of QNEK Productions of Newport.

The postponement will cost the small production company $6,000.

Seventy thousand fans bought tickets to Phish’s last concert this weekend, and many thousands more were expected to show up without tickets. Traffic was so congested that police on Saturday began turning away fans long before they reached the concert site, even those with tickets.

The traffic was relatively slow in the border village of Derby Line, where the Haskell Opera House is located.

But Leimer said she canceled the show because her cast, crew and some audience members would have to travel through the traffic jam to get there.

“Most of my audience comes from Burlington and elsewhere,” she said. She also had a bus coming from White River Junction.

Leimer had arranged to do the show in January, months before the Phish festival was announced.

The rescheduled shows are 7:30 p.m. on Aug. 19, 20 and 21, with a matinee at 2 p.m. Aug. 21.
