Stevie Nicks: School of Rock crowd surprised with Rhiannon performance

The young cast members of Broadway’s School of Rock are rockers in their own right (they play their own instruments on stage every night), but the cast and crowd at Tuesday night’s performance were treated to a performance from a real-life rock icon.

Stevie Nicks came on stage during the show’s curtain call for a surprise performance of “Rhiannon,” backed by the young stars in the show’s band.

“To be in the presence of these kids that are so amazing that honestly sometimes I close my eyes and I’m not sure that it’s not Fleetwood Mac,” she said after the song. “It’s very trippy. They are so good.”

According to the Associated Press, Nicks saw the show on opening night and came back to see it again Tuesday. Her songs are featured in the musical, as well as the 2003 Jack Black-starring film it was inspired by.

Her performance helped to raise money for Broadway Cares/Equity Fights Aids, which provides financial support for people with AIDS, HIV, and HIV-related diseases. “It’s not work, it’s just great fun … so it’s a great, easy way to make money to give to people that really need it,” she told the AP.
