Originally part of "The Saturday Show" from November 2002 until the series ended, this spin-off music strand for Saturday mornings has an extended format and exclusive preview performances from artists soon to be seen on Top of the Pops.

The Saturday Show was a BBC children's Saturday morning show that first aired in 2001, replacing the popular Live & Kicking. It had a mix of audience participation, cartoons, games and gunge. Initially it was presented by Dani Behr and Joe Mace. They left in 2002 and were replaced by Fearne Cotton and Simon Grant. In 2004, Cotton left and Grant was joined by Angellica Bell and Jake Humphrey, who made up the final team of presenters until the programme finished in September 2005.

Suspect is a Whodunit crime mystery program on the children's television channel CBBC. Children attempt to solve crimes committed at the fictional Kilcrammond House Hotel to gain admittance to the Academy of Criminal Investigation. The show is presented by Simon Grant who plays the part of the hotel manager. The show uses a fictitious crime, which the children must solve. Most crimes have managed to relate to children in some way. There have been various crimes, from theft to sabotage, forgery to food poisoning. The children then attempt to solve the case. They however, know that the offender is one of four presented to them at the start. The children get the chance to use forensics equipment, to check fingerprints, and soil samples. They have the chance to talk to 3 of the 4 suspects, before making their final decision. If the children are correct, they receive entry in to the ACI.
