The fourth series takes on a slightly different format - although Rolf is joined each week by Keith Harris, each episode features a different musical guest. This time The Nolans tag along on a visit to Balfour Middle School in Brighton.
Rolf gets to play pirate, the Dooleys perform a song, and Keith Harris is joined by Cuddles as they all visit St. Margaret's Church of England Junior School in Durham.
In the last episode of the series, the group Darts join Rolf and Keith in a trip to Ipswich. The schools taking part are Britannia Road School and Copleston High School.
