Cap'n Bill is called "Ringo" by both Dino and the Library Lady, the latter of whom seems to actually mistake him for Ringo Starr, mentioning The Beatles and their album 'Sgt. Pepper's Lonely Hearts Club Band'. The iconic 'Sgt. Pepper' album was released in May 1967, just a few months prior to this August 25, 1967 episode of "Cap'n Bill and His Sea Pals". On the album cover, The Beatles wear brightly-colored, military-style marching band outfits. The joke is that Cap'n Bill, with his long "hippie" hair and his white nautical uniform, resembles one of the 'Sgt. Pepper'-era Beatles, although neither Ringo nor any of the others had long blond hair. (The Library Lady and Cap'n Bill both admit that their favorite Beatle is Paul McCartney.)
This special episode is a follow-up to Cap'n Bill and His Sea Pals (2021), which introduced the 1960s "Cap'n Bill" program. While that previous show presented a vintage episode of "Cap'n Bill and His Sea Pals" ostensibly broadcast on March 19, 1962, this episode skips ahead to the Summer of Love, showcasing an episode of "Cap'n Bill" ostensibly broadcast on August 25, 1967. As a sign of the times, Cap'n Bill has embraced some of the '60s counterculture, growing his hair long and endorsing Psychedelic Flakes breakfast cereal, while the rest of the "Sea Pals" gang mock "hippies" like him or mistake him for The Beatles' drummer Ringo Starr.
Returning characters from "Cap'n Bill and His Sea Pals" include sea captain host Cap'n Bill ("Your Ol' Buddy"), Rat Pack-inspired Dino ("Playboy Tuna"), fish-woman The Magnificent Mrs. Monkfish ("Nightclub Comedienne"), the rage-filled Library Lady ("Hates Loud Talkers"), and animal expert-slash-Polish sausage manufacturer Dr. Abramowicz ("Municipal Zoo").
Little 'Tinker (1948) and Bride and Gloom (1954) are presented in notably unrestored prints, and neither had been released by Warner Bros. as part of an animation collection on DVD or Blu-ray at the time of this episode's initial broadcast. The MGM cartoon "Little 'Tinker" had been released as a bonus feature on the 2004 DVD of The Bachelor and the Bobby-Soxer (1947), but like many MGM shorts hadn't gotten the digital restoration treatment given to, say, the Warner Bros. Looney Tunes library. "Bride and Gloom" is presented in an old a.a.p. television print, as it (like all of the 1950s Popeye cartoons) had not yet been restored through the partnership between Warner Media and King Features. It hadn't been released on an "authorized" Warner disc, though the short was available on public domain DVD releases.
Cap'n Bill and Dino attempt to build an electric guitar as their do-it-yourself project (encouraging kids at home to follow along). Cap'n Bill notes that he used to play only acoustic guitar, but had decided to switch over to electric, following in the footsteps of "Robert Dylan". Folk singer Bob Dylan caused quite a stir when he switched from his simple acoustic style to a more "rock 'n' roll" electric sound with a full band, beginning with his 1965 album 'Bringing It All Back Home'.
