Legendary rock band Sum 41 is on their farewell tour celebrating their final album, “Heaven :x: Hell.” , and Las Vegas is the pinnacle stop on the tour. You won’t want to miss out on Sum 41 in concert as well as their hits like “In Too Deep,” “Still Waiting,” “With Me,” “We’re All to Blame,” and many more.  Ever wondered where the name “Sum 41” came from? The band started on the 41st day of summer for them, aka the last day of school before summer break for the then-high schoolers.  Although the band is “disbanding,” you still have an opportunity to catch them live in Las Vegas. The Canadian pop-punk band was formed in 1996, and its members are Deryck Whibley, Dave Baksh, Jason “Cone” McCaslin, and Steve Jocz.
