Pull up your leg-warmers and break out the boombox! Melbourne's longest running and most-beloved weekly improv show is turning eight years old, and to celebrate they're heading back to the 1980s!

On the back of a smash hit Melbourne Town Hall season at this year's comedy festival, The Big HOO-HAA! takes to the Howler stage for a special, one-night-only improvised comedy extravaganza.

Stepping back in time to compete for your laughs are a who's who of Melbourne's funniest improvising punchline-slingers. Expect quick-fire improv games, hilarious songs created on the spot, and most importantly - big, BIG hair.

This show always sells out, so don't miss out on a birthday show that's bigger, bolder and better than anything you'll see this year. A Flock of Seagulls couldn't hold back this team of off-the-cuff comedy maestros!
