Matthew has confirmed via his Twitter that he will take part in Celebrity Mastermind.

• I’m doing Celebrity Mastermind for charity. My subject has been confirmed: the life and music of Oasis. Fingers crossed!
• I’ll let you know when it’s on and you can all let @liamgallagher know. I’m sure he’d love to watch it…

Here is some information on the show I found:

Four contestants (in later rounds of the competition the number is occasionally five) take it in turns to answer questions over two rounds against the clock. The first two-minute round comprises questions on each contestant’s chosen specialist subject and the second two-minute round tests general knowledge.

Thanks Lewis Lovers!
