V.impressed. Have used green screen a bit and have found the ay to get rid of creases is to stand the subject as far away from the green screen as possible then use the camera fairly close to subject or else zoom into subject. Depends on size of room!! If you give it as big an exposure as possible (and compensate by keeping the lighting fairly low) then the depth of field will be small ie the green background will be out of focus and the creases will not show up at all. The other thing that works pretty well is to put a light between subject and screen which helps separate subject from background cleanly and also avoids that sort of 'black outline' effect that can be caused by shadow of subject on screen if you only use lights from the front. Anyway, these only minor ideas to try next time - I really enjoyed watching it. Mind you, can't help thinking Graham looks better on the radio...... I really thought it was great! V.impressed.
