Tonight's episode of Saturday Night Live should be must-see TV, with expected coverage of the last Presidential Debate plus an A-list host and musical guest.

Saturday Night Live will likely feature a cold-open centered on the final Presidential Debate between Hillary Clinton and Donald Trump, as we saw with the first two. Millions will be tuning in to see how SNL lampoons the debate, especially Alec Baldwin's portrayal of Trump.

This episode will also be a big one considering the caliber of the host and the musical guest, Tom Hanks and Lady Gaga. Hanks is coming off his latest movie, Sully, which has grossed over $119 million at the box office. Gaga just released her fifth studio album, Joanne, which is currently no. 1 on iTunes and Amazon.

As usual, tonight's episode of Saturday Night Live begins at 11:30 p.m. ET/PT on NBC.

If you cannot watch it on cable television, there are still options to watch it online. Those who have cable can simply go to NBC.com/Live and input their cable subscription information to get a HD live stream of SNL.

But if you don't have cable and still want to watch Hanks and Gaga live, you can sign up for a free trial of Sling TV. Choose the "Sling Blue" option and you will be able to get a free live stream of NBC.

Clips of the Hanks/Gaga episode will be available on YouTube, Hulu and NBC.com Sunday morning on the respective Saturday Night Live pages.
