I think the best thing is to NEVER say "I."
"We are very fortunate..." "We will be hearing some of the finest ..."
What I have to remember, don't say "so, without further ado..."
Of course, "the bathrooms/toilets/loos are located ...."
For small shows, "tonight's fabulous volunteers are ...." "On sound, hard-working ..........."
And for touring musicians, give some of their next gigs, so folks can tell their friends.
I saw the wonderful Gordon Bok last night and the great MC did almost every one of these things!! Congrats to the Portand FMS!
