Allen Klein: Allen Klein (December 18, 1931 July 4, 2009) was an American businessman, music publisher, writers' representative, filmmaker and record label executive, most noted for his tough persona and aggressive, innovative negotiation tactics, many of which established higher industry standards for compensating recording artists.  He founded ABKCO Music & Records Incorporated.  Klein revolutionized the income potential of recording artists, who previously had been routinely victimized by onerous record company contracts.  He first scored massive monetary and contractual windfalls for Buddy Knox and Jimmy Bowen, one-hit rockabillies of the late 1950s, then parlayed his early successes into a position managing Sam Cooke, and eventually managed the Beatles and the Rolling Stones simultaneously, along with many other artists, becoming one of the most powerful individuals in the music industry during his era.

Somewhere in the Sun... Best of the Dream Academy: Somewhere in the Sun... Best of the Dream Academy is a compilation album released by The Dream Academy in Japan in 2000.  The compilation album contains the extended version of "Life In A Northern Town" and an acoustic version of "The Party" rather than the more common versions.  At the time of its release, Nick Laird-Clowes revealed that the band actually had no involvement with the album, and he went on further to say that they weren’t even informed by Warners that a compilation album was being made.  His former label boss, Alan McGee, then of Creation Records, was the one who actually brought him home a copy when he was visiting Japan on business.  According to Kate St John, around the same time that this album was being made, Warner Brothers were considering a US compilation album, but they and the band decided to re-issue their first album, "The Dream Academy".

No songs from Sonia's first studio album, "Everybody Knows" (which was released on a different record label), are included.  Prior to the "Greatest Hits" release, Sonia also recorded the Motown-influenced songs "Dancing In the Driver's Seat" and "Your Heart Or Mine", both written by Barry Upton and Gordon Pogoda, but ultimately the record label chose to include no new songs for the album, so these recordings remain unreleased.
