* HeyItsThatGuy - Barney Harwood, one of the current presenters, was already well known as the host of Prank Patrol, Basil's Swap Shop, and other CBBC shows, before taking on the Blue Peter role.
** In fact he presented the Sunday evening radio equivalent ''Go for It!'' on BBC Radio 4 for some years - a long-running childrens' magazine format show just after the Archers at 7:15pm.
** Peter Purves is another example, having previously been a companion in ''Series/DoctorWho''.
