There’d be no Saturday Night Live to premiere in 1975 without Second City’s legendary improv troupe — no Gilda Radner, John Belushi, Dan Aykroyd or Bill Murray … no Emily Litella, Samurai Dry Cleaners, Todd the Nerd or the Blues Brothers. Now, on the 60th anniversary of the world’s most-famous comedy training ground, today’s talent brings back Greatest Hits from the ‘70s, with sketches and original songs revived from the archives and rebooted and re-imagined for our far-out times. Plus, you’ll see some groovy new Chicago-style improv from the current cast at UP Comedy Club. Can you dig it?  Discount tickets on Goldstar are only $13 plus service fees for performance dates throughout May.
