“Go Tell it on the Mountain,” everyone from Frank Sinatra to Jewel has urged listeners with various recordings of the famous African-American spiritual. Tonight’s your chance to take them up on it, metaphorically, and tell any jokes, quips, stories, or dictums with a mic in your hands to the crowd at New York Comedy Club. There are open slots from 5 to 7 pm and it’s $5 to join the fun.
