Taylor Swift will be offering live video streams of two songs she'll perform Saturday (May 21) at her "Speak Now ... Help Now" charity concert at Nashville's Bridgestone Arena. Originally scheduled as a dress rehearsal for the North American leg of her Speak Now World Tour, Swift decided to turn the Nashville concert into a public event to raise money for tornado victims. The video stream will include information on how to make a donation. All proceeds from the concert's ticket sales will go directly to help victims via the Speak Now ... Help Now fund established through the Community Foundation of Middle Tennessee. The live streaming begins at 9 p.m. CT at www.Taylorswift.com, Ustream.tv/taylorswift, Facebook.com/TaylorSwift and MySpace.com/TaylorSwift. She begins her tour May 27 in Omaha, Neb.
