Did you ever do any?
I remember even though i was young, i was 'mature' and i got the priv. of doing Microphones on certain occasions, helped the brother doing carpark e.t.c
I used to hate Mic's at our hall, they had cable attached so you were always tripping over this huge cable, or a sister would have it in her hand, then pull it, so you'd end up with this thing around your legs, basically attaching you to her. They have wireless ones there now...damn i missed out! Also helped putting the micophones away.
Car Park was nearly always boring as hell, but beat sitting in the Kingdom Hall - some bro's used to play music if they couldn't pickup the meeting via the radio thingy, but it was often Kingdom Melodies
