Hosted by Aamer Haleem, the show documents attempted reunions of formerly popular musical groups for special concerts in either London or Los Angeles.

A show normally consists of the crew first hunting down the ex-members of the band (often first in a ruse) one-by-one, and convincing them to agree for the one-time concert.

The final segment is the formal reunion of the band in the rehearsing studio, and a joint interview about having disbanded.

The artificial and invasive nature of the reality show, and the contractual arrangements behind it, have been criticized.

Kurt Harland of Information Society detailed his own negative experiences with the program, and how his experiences differed from the portrayal of events as broadcast, on his website; citing examples of misinformation, poor background research and manipulation from the show's production crew, regarding the show to have been more interested in sensationalising his band's breakup than a genuine reunion.
