Springsteen was backed by horns, fiddles, an accordion and pedal steel guitar, among other instruments, as he performed a range of legendary folksinger Pete Seeger songs during a benefit concert at Convention Hall Thursday night, the New York Daily News reported Friday.
Springsteen let loose with a range of styles from bluegrass to funk but did not play any of his own rock classics during the two-hour performance.
He dedicated Seeger's anti-war ballad "Mrs. McGrath" to Cindy Sheehan and revamped the lyrics of "How Can a Poor Man Stand Times Like These and Live" to relate to the suffering of New Orleans residents after Hurricane Katrina.
"The Seeger Sessions" will be released nationwide Tuesday.
