The event serves as one of the marquee attractions for the Just For Laughs festival, which continues through July 26. Following a sold-out engagement in Vancouver earlier this year—his first Canadian performance since 1978—Letterman returns to the country to discuss his four-decade career that redefined the late-night landscape.

Tickets for the evening are currently available through the official festival website at HAHAHA.COM. The pairing of Letterman and Arnett offers a rare look at two distinct generations of comedic influence, anchored by the presence of Shaffer, who provided the musical backbone for Letterman's television tenure for decades.
