Context paragraphs:
Alan W. Pollack: Alan W. Pollack is a musicologist.  He is best known for having musically analysed every Beatles song released.  He started the task in 1989 and finished in 2000, with 187 original songs and 25 cover songs.  The analyses have come to be known as the "Notes on ..." series, as each is entitled "Notes on 'Love Me Do'", "Notes on 'Help! '" and so on.  The notes were released weekly, usually on Wednesdays, on the rec.music.beatles usenet group.  Pollack's individual song analyses and comments on unifying themes in the Beatles' work were later incorporated by musicologist Walter Everett in his two-volume study "The Beatles as Musicians".  The "Notes on …" series is also among the "Recommended Resources" in author and critic Kenneth Womack's 2014 book "The Beatles Encyclopedia".

Beatles (song): "Beatles", written by Sven Olov Bagge and Claes Bure, was the song that, performed by Swedish dansband Forbes, won the Swedish Melodifestivalen 1977.  The song's lyrics are about the popular 1960s British rock group the Beatles and include the phrase "Yeah, yeah, yeah" as an homage to the Beatles song "She Loves You".  Forbes took the song to the United Kingdom for the Eurovision Song Contest 1977, with Anders Berglund as conductor.  The audience cheered at the song, not unexpectedly since the contest took place in the United Kingdom, but the jury had another opinion.  The song finished last, with only two points, from West Germany.

Love You To: "Love You To" is a song by the English rock band the Beatles from their 1966 album "Revolver".  The song was written and sung by George Harrison and features Indian instrumentation such as sitar and tabla.  Following Harrison's introduction of the sitar on "Norwegian Wood" in 1965, it was the first Beatles song to fully reflect the influence of Indian classical music.  The recording was made with minimal participation from Harrison's bandmates; instead, he created the track with tabla player Anil Bhagwat and other Indian musicians from the Asian Music Circle in London.

Sekret (band): Sekret (Russian: Секрет , lit.: "Secret") was a Soviet Russian rock and roll band founded in 1982 in Leningrad.  The band's musical style and image drawn a heavy inspiration from 1950's and 1960's western music, The Beatles in particular.  The band's name was inspired by the Beatles song 'Do You Want to Know a Secret? '.  Secret called themselves a "Beat Quartet" and were a part of Soviet rock and roll revival of 1980's, along with Bravo.

The Inner Light (song): "The Inner Light" is a song by the English rock group the Beatles, written by George Harrison.  It was released on a non-album single in March 1968, as the B-side to "Lady Madonna".  The song was the first Harrison composition to be issued on a Beatles single and reflects the band's embrace of Transcendental Meditation, which they were studying in India under Maharishi Mahesh Yogi at the time of the single's release.  After "Love You To" and "Within You Without You", it was the last of Harrison's three songs from the Beatles era that demonstrate an overt Indian classical influence and are styled as Indian pieces.  The lyrics are a rendering of a poem from the Taoist "Tao Te Ching", which he set to music on the recommendation of Juan Mascaró, a Sanskrit scholar who had translated the passage in his 1958 book "Lamps of Fire".

The Beatles' Story: The Beatles' Story is the sixth album by the Beatles in the United States, issued on 23 November 1964 by Capitol Records in both mono and stereo formats (although the mono was merely a fold-down of the stereo mix).  It is a documentary double album featuring interviews, press conferences, snippets of original or orchestral versions of Beatles songs with voice-overs.  The easy listening excerpts were created, produced and arranged by Stu Phillips with the Hollyridge Strings originally recorded for the first Capitol Records' "Beatles Song Book".

Lamps of Fire: Lamps of Fire - the Spirit of Religions is an anthology of religious writings compiled, and often translated, by Juan Mascaró.

All You Need Is Ears: All You Need Is Ears: The inside personal story of the genius who created The Beatles (ISBN  ) is the 1979 memoir of The Beatles' producer George Martin, co-authored by Jeremy Hornsby.  The book was republished in 1994.  The title is a play-on-words to the Beatles song "All You Need is Love".

Juan Mascaró: Juan Mascaró (December 8, 1897 – March 19, 1987) was a Spanish translator born in Majorca to a farming family.  He is responsible for one of the most popular English translations of the Hindu text Bhagavad Gita, and of some of the major "Upanishads".  He also translated a key Buddhist text, "Dhammapada", into English from Pāli, which was published in 1973.  His first work, "Lamps of Fire", was a collection of religious and spiritual wisdom from across the world; a selection from the book inspired the Beatles song The Inner Light.  Though his native tongue was Catalan, he translated into English.

Beatallica: Beatallica is a mash-up band that plays music made from combinations of songs of the Beatles and Metallica.  A Beatallica song is typically a blend of a Beatles song and a Metallica song with a related title (e.g. "The Thing That Should Not Let It Be", combining The Beatles' "Let It Be" and Metallica's "The Thing That Should Not Be" or "And Justice for All My Loving" combining Metallica's "And Justice for All" and the Beatles' "All My Loving"), though sometimes just a Beatles song will be used as a basis with modified lyrics.  The lyrics slip back and forth between the two songs, or occasionally neither, in lieu of original lyrics comically referencing Metallica, heavy metal music, or the heavy metal community.  While the scansion and melody are usually Beatles-based, the music is played metal style with some Metallica riffs and solos thrown in.  Consistent quirks made in the lyrics also criticize glam metal much in the fashion that thrash metal fans would do, as well as many references to blood.  Their version of "I Want to Hold Your Hand" called "I Want to Choke Your Band", is an example of their criticism towards glam metal.
