Rick it depends as I did the majority of my gigging in the States. California, Oregon, Washington and overseas. I would say I use the mic when necessary but predominately let the music mix do the talking. If everyone is having fun and I dont lose folks there isnt always a need to chatter on the mic. Im quick with comment as you may have noticed on here stuff just flows but I dont have to use it much of the time. If Im encouraging the group to let loose I have my tricks and during a particular moment will get the crowd roaring either by making fun of myself or joking with the bride or groom or client. Some ad lib for sure.
Some nights the crowd is so energized by the music that I dont have to use the mic much at all. I MC'd all my wdddings in the states and around 2-3 out of 10 up here as I offer it and have a reputation for being very thorough with the MCing chore. I recently did a MC only gig which was my first without a system which felt odd not attending to the music as well. I also interact out in the crowd as you mentioned as I might put a combo mix on now and again or a longer song. I dont just pick music and anchor myself to the console with my eyes locked on the screen. Thats why I am able to see the instant need for a song or change on the fly.
