Yes, several times. Worked for a stage lighting company in the uk which supplied lighting equipment to tv and film studios. The job entailed visiting the studios to estimate their lighting requirements. As a perk also scored tickets for tv shows which were around at that time.
Yes, but only in the audience of the Midday Show with Ray Martin, & another Midday show, with another host. & also Rumpus Room, when my friend was taking her little daughter to be on the show, not long before the show ended, in fact.
