MONTREAL — Satirical heavy-metal band Spinal Tap, Emmy Award-winning “Will & Grace” thesp Megan Mullally, comic talkshow host Jon Stewart and funnyman Jeff Foxworthy will top the lineup for this year’s Just for Laughs Comedy Festival in Montreal.

Programming for the 19th edition of the Canuck laugh fest, which runs July 12-22, was unveiled at a press conference in Montreal by Just for Laughs chief operating officer Bruce Hills.

Spinal Tap — featuring Michael McKean, Christopher Guest and Harry Shearer — along with Mullally, Stewart and Foxworthy will each be hosting galas.

Performers at the galas will include Darrell Hammond from “Saturday Night Live,” Ron James from the Canadian sitcom “Blackfly” and Bill Engvall and Anthony Clark from “Yes, Dear.”

Other thesps and comics set to make the trek to Montreal this summer include Gabe Kaplan (“Welcome Back Kotter”), John Fugelsang (“America’s Funniest Home Videos”), Joy Behar (“The View”) and Marla Sokoloff (“The Practice”).

‘Lowest’ prepped

Scott Thompson from the Kids in the Hall will be bringing his new one-man show, “The Lowest Show on Earth,” and the fest will also host the North American preem of the West End hit “Puppetry of the Penis.”

The numerous club shows include the Nasty Show with Bobby Slayton, Queer Comics, Laugh-rodisiacs: The Relationships Show, Bubbling With Laughter, New Faces of Comedy (one of the most popular shows for talent scouts) and the Bar Mitzvah Show.

Multinight, nonstandup shows on the bill include light and music gala “Momix in Orbit,” motherhood comedy “Mom’s the Word” and Nia Vardalos’ one-woman show “My Big Fat Greek Wedding” (which is being made into a pic by Tom Hanks’ production company Playtone Co.).

Films, too

Festival will also have a strong film component. Last year, Just for Laughs merged with the Fantasia film fest, and the two will present a selection of comic pics, including the feature series “Comedia” and the three short-pic program composed of “Eat My Shorts,” “Eat My Twisted Shorts” and “Tout Court.”

In addition, the festival has a number of events tailored to the more than 1,000 industryites who attend each year. This year’s industry sidebar, sponsored by Variety, includes Andy Kindler’s sixth annual State of the Industry Address, “The Man Show” with Jimmy Kimmel, Adam Carolla, and Daniel Kellison, and “The Festival Game Show” in which U.K. comic Johnny Vegas sets up a game pitting the Suits (industry execs) against the Creatives (the comics) in a gameshow parody.
