http://nationalkaraokeleague.com/ I posted this last season in Singer's forum and only got 2 responses. Now a new season starts in Feb. The rules are to sing a song and also to add a performance to it. Some people went all out and did full costumes while we kept it tone down and just did minimal dressup.
Last season a guy won a round by singing Q Lazarus' Goodbye Horses and portraying Buffalo Bill from Silence of the Lambs. Since it was halloween week a team won a group round with their Rocky Horror Time Warp in all costume.
One team did my idea of MIA's Paper Planes where someone sings and teammates threw paper planes around while another person had a rifle and cash for the chorus.
Has anyone heard of a karaoke league night in your area? Anyone care to join in this brainstorm session to think something would be funny or witty to perform?
