The tour also marked the first time that The Beach Boys had played at the Hollywood Bowl since 1967, having sold it out both times.  Brian Wilson stated that this Beach Boys tour, and the album associated with it, "That's Why God Made the Radio", which was released in June 2012, is dedicated to the memory of his two brothers: Carl who died of cancer in 1998, and Dennis, who drowned in 1983.

Beach Boys' Party!: Beach Boys' Party!  is the tenth studio album by American rock band the Beach Boys, and their third in 1965, consisting mostly of cover songs played with acoustic instruments, mixed to sound rough and unfinished.  The album was actually recorded in a music studio, presented as an impromptu live recording of a party, with informal chatter by friends and family overdubbed later.  The album reached No. 6 in the US and No. 3 in the UK.  It spawned one hit single, a cover of the Regents' "Barbara Ann", which reached No. 2 in the US.  In the UK, it became the Beach Boys' highest performing single yet, reaching No. 3 in early 1966.

Here Comes the Night (David Johansen album): Here Comes the Night is the third solo album for New York Dolls lead singer David Johansen.  Released in 1981, Blondie Chaplin (from Beach Boys fame) serves as the producer for the album (for Blondie Chaplin's writing contributions, his middle name William is used and he is listed as "Bill Chaplin").  Although Chaplin was a former Beach Boys member, the album and title song, "Here Comes the Night", does not have any relationship to the Beach Boys song, "Here Comes the Night".

Musicianship of Brian Wilson: The songwriting of American musician Brian Wilson, co-founder and multi-tasking leader of the Beach Boys, is widely considered to be among the most innovative and significant of the late 20th century.  His combined arranging, producing, and songwriting skills also made him a major innovator in the field of music production.  In a 1966 article that asks "Do the Beach Boys rely too much on sound genius Brian?"  brother and bandmate Carl Wilson responded that every member of the group contributes ideas, but admitted that Brian was most responsible for their music.  Dennis Wilson is quoted: "Brian Wilson "is" the Beach Boys.  He is the band.  We're his fucking messengers.  He is all of it.  Period.  We're nothing.  He's everything."

It was predicated mainly on the Beach Boys' Brian Wilson (especially the 1966 album "Pet Sounds") and composer Burt Bacharach, in addition to producers Henry Mancini, Lee Hazlewood, Phil Spector, and singer Scott Walker.

Henry Mancini: Enrico Nicola "Henry" Mancini (April 16, 1924 – June 14, 1994) was an American composer, conductor and arranger, who is best remembered for his film and television scores.
