For safe Karaoke, bring along your own microphone condom.
I sometimes sing a few tunes at our local pub’s Tuesday night Irish sessions, while the band takes a break to schmooze with the customers. For more than a year during COVID they stopped doing it. When they resumed, the first time they called me up I made a show of putting one on the mike as a gag. Got a good laugh!
Do you do barbershop?
