The Undergraduate Council will kick off its annual Springfest celebration tomorrow afternoon in the Mac Quad-but with a few significant changes from last year.

This year's musical lineup will include only student bands, unlike last year's concert that featured popular swing band "Big Bad Voodoo Daddy."

Without a big band to finance, this year's Springfest will cost the council less than half of last year's budget-decreasing costs from $40,000 to about $15,000.

"I'm sure the student bands will be great," said Melissa A. Eccleston `04, co-chair of the council's Campus Life Committee (CLC). "Plus, we freed up more money for other aspects like amusements."

For example, Eccleston said, the council contracted with a more expensive company to provide rides, in the hope that students will have more to do at Springfest than just listen to music.

Last year's rides never arrived at the event after a legal issue arose between the company and the city of Cambridge.

"Even though we're not having a big band, it should still be a great time," Eccleston said.

The show will be hosted by Harvard's Instant Gratification Players (IGP), a student improv-comedy troupe.
