The Laughing Penguin returns to Edinburgh for the third year with its annual Laughing Penguin Showcase. Each day, we bring you three top performers all held together by co-founder and resident MC Tony Jameson. Last year's show included performances from Gary Delaney, Chris Ramsey, Nathan Caton, Dag Soras, Joe Lycett, to name but a few. This year promises to be even bigger and better.
