I think the call in show idea is pretty good, perhaps have a quiz, finish the lyrics or something or maybe even a different game each week. It will get the listeners involved too which I'm sure they'll love! I'll probably listen in too.
Yeah, to avoid this they'll have to ring them up just before and discuss what they're going to say before. It will also be better if it was live, and not pre-recorded because I'm sure HxL management say you have to record it before going on air. If it was recorded then the 'live' feeling wouldn't be that good.
And yeah, Richie your show with Ryan (Chicken) was good when you recorded the prank calls live but then you had to pre-record them and it just wasn't the same feeling as the others knowing that they were pre-recorded.
