Soundgarden singer Chris Cornell was joined by the other three members of the band for a surprise six-song set during Cornell's solo show on Monday night (November 12th) at Bowery Ballroom in New York City. According to Brooklyn Vegan, the full band played six songs: "Fell On Black Days," "Blow Up The Outside World," "Black Hole Sun," "Outshined" and new tunes "Halfway There" and "Black Saturday."

Cornell set up the show as a benefit with all proceeds going to the victims of Hurricane Sandy, which devastated the New York/New Jersey area two weeks ago. There were rumors that the rest of Soundgarden would show up at the gig.

• Earlier in the evening, the band played a 10-song set for the Live On Letterman webcast, while also taping an appearance on Late Show With David Letterman which aired that night.
• The webcast featured several songs from the band's early days and Cornell told us that he would love to delve even deeper into the band's catalog: "We have such a long history, and a lot of songs that we either haven't played in a long time and some we never really have played much live. So we have like a huge list of things. It'll be nice at some point to just be able to play kind of anything at any time."
• Soundgarden was in New York to promote the Tuesday (November 13th) arrival of King Animal, the band's first new album in 16 years.
• The group was scheduled to play a full headlining show on Tuesday night at an "intimate" New York club, followed by similar gigs in Toronto on November 16th and Los Angeles on the 27th. A winter North American tour kicks off on January 18th, 2013 in Washington DC.
