Watch Taking Back Sunday perform 'Set Phasers to Stun' with Spencer Chamberlain

The first footage of Taking Back Sunday performing with fill-in vocalist Spencer Chamberlain has surfaced online.

The former Underøath lead is currently performing on a run of shows with the band, with regular frontman Adam Lazzarra taking some brief time off due to the birth of his second child.

"Spencer Chamberlain, a long-time friend of Adam, has willingly stepped up to fill in and give the new father more time to stay in the hospital with his family," reads a statement from the band.

"Spencer was the frontman of Underoath for 10 years and is currently working on a new project called Sleepwave. The band is excited to have him and look forward to Spencer and John trading lead and backing vocals at the upcoming shows."
