Wesley Tuttle: Wesley Tuttle (born December 30, 1917 in Lamar, Colorado; died September 29, 2003) was an American country music singer.  He was raised in California and took up music at age four, relearning to play the guitar and ukulele after losing all but the thumb and one finger on his left hand.  He contributed the yodeling to the "Silly Song" in Walt Disney's "Snow White and the Seven Dwarfs", and later backed Tex Ritter on guitar.

A Snow White Christmas: A Snow White Christmas is a Christmas animated television special produced by Filmation and telecast December 19, 1980, on CBS.  It is a sequel to the fairy tale "Snow White", unrelated to Filmation's other sequel to "Snow White" titled "Happily Ever After" (1990).  While this is a sequel to the original story and not the 1937 Disney film, there are some similarities.  The film's plot revolves around the return of the Wicked Queen, who is unexpectedly brought back to life and casts an evil spell that freezes the entire land.  It is up to young Snow White, the daughter of the original Snow White aided by the seven giants, to defeat her once-and-for-all and save the kingdom.

Reggie the Rabbit: Reggie the Rabbit is the mascot of the South Sydney Rabbitohs.  The rabbit took lifesize form in 1968 when celebrity fan Don Lane brought back a suit from the US in time for the 1968 grand final against Manly Warringah Sea Eagles, won by the Bunnies 13–9.  Perhaps the most notable of the early Reggies was the club's groundsman Reg Fridd.  Standing just over four feet tall, the Rabbitohs lured the diminutive Kiwi from a touring production of Snow White and the Seven Dwarves, the same troupe that had yielded the second Reggie, Roscoe Bova, tragically killed in a car accident in the early 1970s.  Most teams in the National Rugby League maintain mascots.  But none do the sort of charity work as Reggie and none dare venture to opposition grounds as he does.  Yet for the current Reggie, Charlie Gallico – a sub-five footer who runs a panelbeating shop on the side – it's all part of the job.  For five years little Charlie has been quietly and anonymously volunteering his services to his club and community to maintain a sideline alter-ego as one of sport's most enduring symbols.  During 2000 and 2001, when Souths was excluded from the NRL, Anth Courtney was Reggie Rabbit appearing at the second Town Hall rally and at games at Redfern Oval as well as being active in travelling extensively around the state to attend fundraisers as Reggie Rabbit.

Heigh-Ho: "Heigh-Ho" is a song from Walt Disney's 1937 animated film "Snow White and the Seven Dwarfs", written by Frank Churchill (music) and Larry Morey (lyrics).  It is sung by the group of seven dwarfs as they work at a mine with diamonds and rubies, and is one of the best-known songs in the film.  The melodic theme for "Heigh-Ho" might have been inspired by Robert Schumann's composition for piano "The Happy Farmer, Returning From Work" from his 1848 work "Album for the Young", Opus 68.  The other Dwarf Chorus songs are ""Bluddle-Uddle-Um-Dum"" (the washing-up song) and ""The Silly Song"".
