Amanda Holden reached for the golden buzzer on Britain’s Got Talent to propel a teenage rock band through to the semi-finals.
The young four-piece band, aged 14 between 15, were compared to successful British rockers Busted as judges hailed their audition.
Holden ensured their place in the live shows with the golden buzzer, and praised the "absolutely incredible" act.
Chapter 13, comprised of performers from a production of School Of Rock, wowed all four panellists who were impressed with the musicianship of the youngsters.
Band members Jacob, Noah, Tom and Jake were feted for their performance of a rock medley of Stevie Wonder hits.
Holden said: "I don’t think I’ve ever seen four young musicians so together.
"The drummer, you were amazing. The guitar playing was spot on.
"Some of the faces you were pulling were fantastic. I just think you were absolutely incredible."
