Remember this rather weird appearance of an Elvis impersonator at a Labour photo call?
Alistair Campbell organised the presence of The Pelvis (aka Mark Wright) at Lodge Park Technology College in Corby, thinking it would boost Gordon Brown's election campaign.
Now Corby borough council is investigating whether the performance at the weekend breached the Licencing Act. The college is not allowed to permit performances of live music before 6pm.
Corby council has contacted the head teacher, Tom Waterworth, to demand an explanation.
Under the Act, Campbell, as organiser, and Waterworth, the licence holder, could face criminal prosecution resulting in six months in prison or a £20,000 fine.
The college was unable to get a Temporary Event Notice authorising the performance of music, as plans to allow last-minute event notices were withdrawn by the Goverment this month.
