To celebrate the 50th webcast of CBS Interactive's award-winning live webcast concert series "Live On Letterman", KISS brought its spectacular, larger-than-life extravaganza of music to the world famous Ed Sullivan Theater in New York City. The 48-minute concert was webcast live and is now available on demand on CBS.com.

KISS, in all its bombastic and unstoppable glory, performed fan favorites from their treasure-trove of hits along with "Hell Or Hallelujah", from their new album, "Monster", which came out October 9.

Having already broken box office records set by THE BEATLES and Elvis Presley, KISS celebrates their 40th anniversary in 2013 with more than 28 U.S. gold albums, the most gold records for any American rock band, with 40 million sales in the U.S. and a total exceeding 100 million worldwide. Gene Simmons and Paul Stanley, with longtime members guitarist Tommy Thayer and drummer Eric Singer, return stronger than ever with their new album.

The "Live On Letterman" franchise, which has surpassed 130 million views to date on CBS.com and VEVO, marks its 50th webcast with KISS' performance. Past performances have included some of the most established bands and musicians across the globe, from its first event which featured PEARL JAM to Paul McCartney on the marquee of the Ed Sullivan Theater, FOO FIGHTERS, Katy Perry, COLDPLAY, Adele and more, all staged in an intimate and dynamic setting for worldwide followers to enjoy.

KISS' "Live On Letterman" webcast preceded their appearance on the "Late Show With David Letterman", which was broadcast that same evening, Wednesday, October 10 (11:35 p.m.-12:37 a.m., ET/PT) on the CBS television network. Video footage of that performance can be seen below.
