(CBS) — Outdoor concerts by Pearl Jam and Phish were abruptly halted Friday as storms descended on the Chicago area.

A concert-goer tells CBS 2 that frontman Eddie Vedder and his band Pearl Jam played eight songs before it was announced they stopped playing at around 9 p.m. because of lightning. Pearl Jam resumed their concert at around midnight and played until 2 a.m.

Those who waited patiently for the the band to pick-up where they left off, got a real treat, as Cubs great, Ernie Banks, made a surprise appearance, to help get the concert going again.

Some are blaming the delay on the “Cubs Curse”. Pearl Jam has a new album coming out, and believe it or not, it’s called “Lightning Bolt.”

Phish also stopped its concert at Northerly Island. The nearby parking garage at Soldier Field was opened up for exiting fans.

At the Pitchfork outdoor music festival in Union Park, main act Bjork cut short her evening performance by 30 minutes.
