The Fallout series is famous for its soundtracks, featuring melodies from the ’30s to the ’60s that help mitigate the Wasteland’s terrors. The first season of the Prime Video adaptation embraced this aspect, and the initial episode of Season 2 hints at even more. Music supervisor Trygge Toven incorporates a significant needle drop: “Big Iron,” the 1959 Western ballad by Marty Robbins, which is well-known among Fallout enthusiasts from Fallout: New Vegas.

In the opening episode, Lucy (Ella Purnell) and Cooper (Walton Goggins) find themselves in a precarious situation, with Coop being taken captive by the Great Khan raiders, a faction from Fallout: New Vegas set in the Mojave Wasteland. The gang’s hideout in the show is the Dino Dee-lite Motel, featuring the enormous T-rex where Lucy conceals herself.

Coop and Lucy battle their way to freedom to the tune of “Big Iron,” a track accessible in New Vegas through the radio on your Pip Boy. The game’s soundtrack can be alternated with Mojave Music Radio or Radio New Vegas, making areas swarming with enemies slightly less daunting, just as “Big Iron” adds a surreal touch to the bloody events in episode 1.

Additional tracks featured in the episode include Peggy Lee’s “Cheek to Cheek,” The Del-Vikings’ “Come Go with Me,” The Ink-Spots’ “It’s All Over but the Crying,” and Roy Orbison’s “Working for the Man.” “Big Iron” isn’t the sole Easter egg for Fallout aficionados.

Fallout Season 2 debuts on Dec. 16 at 9 p.m. ET on Prime Video, with a new episode released each week.
