It's weird when singers carry around the mic on the mic stand while they sing. It's like they don't realize that the mic isn't attached to the stand for that specific reason, amirite?

It does look weird, but if they're moving across the stage, maybe they want to stop and sing in another place, in which case they'd need to have the stand with them.

idk if youve ever sang on stage, but it just feels better and makes me feel more compfortabl;e

If the singer gets tired/is lazy, he always has something he can lean on.
