“GLOW: The Story of the Gorgeous Ladies of Wrestling” screens at 5, 8 or 10 p.m. Saturday at The Somerville Theatre.

We still have local roller derby, a proud descendant in the arena of tough women with funny names, but the late 1980s had the genre at a whole different level. Relive the age of the Gorgeous Ladies of Wrestling with Matilda the Hun, Big Bad Mama and more in this documentary directed by Brett Whitcomb. Tickets are $8. The event page is here.

Frosty the Snow Jam, a CRLS a cappella show at 7 p.m. Saturday in The Fitzgerald Theatre at Cambridge Rindge and Latin School, 459 Broadway.

The high school’s winter A Cappella Jam starts with the school’s own four singing troupes: the boys group Bro’Cappella, girls groups Sassafras and Girls Next Door and coed group Pitches and Do’s. It also showcases Bancroft High School’s Chordially Yours; Lexington High School groups Pitch Pipes and Mixed Nuts; The Wayland Madrigals; a new all-male quartet; and Redline,  a professional group. Tickets are $5 at the door.

Loteria! Mexican bingo at 10:30 a.m. and 12:30 p.m. at The Painted Burro, 219 Elm St., Davis Square, Somerville.

It may be too early to sample The Painted Burro’s tequila offerings (the tequila bar opens daily at 5 p.m.), but not to have brunch and play the restaurant’s second-ever round of Loteria, a Mexican game of chance similar to bingo, in the restaurant’s bar and lounge. Gift cards will be awarded as prizes. Call (617) 776-0005 to reserve a space. The event page is here.

Cherubs & Angels of Mount Auburn tour at 1 or 2:30 p.m. Sunday at Mount Auburn Cemetery, 580 Mount Auburn St.

Sunday is forecast to see a high of 41 degrees Fahrenheit – warm enough for an exploration of the grounds of this beautiful, historic cemetery in search of images of celestial beings scattered about in marble and granite, posing proudly on pedestals or tucked into the decorations of monuments. Volunteer docent Rosemarie Smurzynski leads the search for $12, or $7 if you’re a member of The Friends of Mount Auburn Cemetery. The event page is here.

Buskers for the Homeless concert at 8 p.m. Sunday at The Burren, 247 Elm St., Davis Square, Somerville.

As temperatures dip dangerously, musician Tom Bianchi has gathered what is basically an all-star group of buskers to raise money to give to the Somerville Homeless Coalition and “keep our friends and families in need off the streets.” You’ll undoubtedly recognize Dan Blakeslee, Danielle Miraglia, Amy Kucharik, Mike Hastings, Ryan Alvanos and Olivia Brownlee among the musicians, but the show also features perhaps the most famous and storied busker in America: Mary Lou Lord, the Berklee graduate, founding artist of the Kill Rock Stars label and early champion and peer of Daniel Johnston, Big Star and Nirvana.
