I was very excited about this show coming back as I enjoyed it so much last year.  I think the panel is much better this year and I definitely think the right person went last night as his voice just wasn't strong enough.  To be fair he wasn't necessarily going to put his all into it, he was saying from the outset that he would do this, that or the other.  
I deliberately haven't said who left in case anyone is waiting to watch on iplayer, but I will pm you with the answer Joan.
