Rush continue the roll-up to their new R40 Live set with the release of a clip capturing the band performing "Tom Sawyer."

One of several worldwide hits from 1981's Moving Pictures, "Tom Sawyer" helped Rush expand on the commercial momentum they'd attained with 1980's Permanent Waves, and has remained one of the group's most widely recognized songs over the ensuing decades — as evidenced by the goofy South Park intro you can see before the song gets started in the video.

As previously reported, R40 Live commemorates the band's recently concluded run of 40th anniversary dates — billed as their last major tour — by collecting nearly three hours of footage with an emphasis on songs that have "either never been performed before or never been captured on video."

Filmed during a pair of shows at the Air Canada Centre in their hometown of Toronto, R40 Live is being offered in multiple configurations, with fans able to choose between DVD/Blu-ray versions, combo packs or a CD-only package. The set list moves in reverse chronological order, taking fans on a career-spanning journey that begins with selections from 2012's Clockwork Angels and concludes with the band's self-titled 1974 debut.

"Tom Sawyer" is just the latest in a series of pre-release teases from R40 Live, starting with "Roll the Bones" and continuing with "Closer to the Heart" and "Spirit of Radio." With the title's Nov. 20 release still several weeks away, it seems likely fans can still look forward to being treated to another sneak peek or two before it arrives in stores.
