What to do with the new space opened up by the moving Chart Show

With The Chart Show disappearing down a hole round the back of old Mel's place ("moving to Friday teatimes"), Radio One suddenly has a two hour gap in its schedules on Sunday nights.

How would you fill such a space in the schedules?

I can't think of an idea.

Nor could Radio One, it turns out:

Radio 1 has announced a new Sunday show which will replace the current Official Chart slot when it moves to Fridays next month.

Hosted by CBBC presenter Cell Spellman, the new show will split into two parts, one devoted to new pop music with the other playing number one hits.

Spellman said: "The best station on national radio has been responsible for introducing me to so much incredible and varied music over the years, I just hope I can return the favour and help make those car journeys a little more memorable for the listeners with a mix of fun, top tunes and a little bit of cheeky chat!"

The reference to car journeys is a little odd - six on a Sunday is hardly prime Drivetime, is it?
