Question: What founder of ABKCO Music & Records Incorporated had legal fights with the Rolling Stones?

<P0-S0> Sticky Fingers is the ninth British and 11th American studio album by the English rock band The Rolling Stones, released in April 1971. <P0-S1>  It is the band's first album of the 1970s and its first release on the band's newly formed label, Rolling Stones Records, after having been contracted since 1963 with Decca Records in the UK and London Records in the US. <P0-S2>  It is also Mick Taylor's first full-length appearance on a Rolling Stones album, the first Rolling Stones album not to feature any contributions from guitarist and founder Brian Jones and the first one on which singer Mick Jagger is credited with playing guitar. <SEP> <P1-S0> ABKCO Music & Records, Inc. (ABKCO acronym of Allen & Betty Klein and COmpany) is an American major independent record label, music publisher, and film and video production company. <P1-S1>  It owns and or administers the rights to music by Sam Cooke, the Rolling Stones, the Animals, Herman's Hermits, Marianne Faithfull, Dishwalla, the Kinks as well as the Cameo Parkway label, which includes recordings by such artists as Chubby Checker, Bobby Rydell, the Orlons, the Dovells, Question Mark & the Mysterians, the Tymes and Dee Dee Sharp. <P1-S2>  Until 2009, ABKCO administered Philles Records and its master recordings, including hits by the Righteous Brothers, the Ronettes, the Crystals and others (via a licensing deal with EMI Music Publishing, which owned the Philles catalog since the mid-1990s). <SEP> <P2-S0> 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. <P2-S1>  Klein revolutionized the income potential of recording artists, who previously had been routinely victimized by onerous record company contracts. <P2-S2>  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. <P2-S3>  He founded ABKCO Music & Records Incorporated. <SEP> <P3-S0> Charlie Is My Darling, directed by Peter Whitehead and produced by the Rolling Stones' manager Andrew Loog Oldham, was the first documentary film about the Rolling Stones. <P3-S1>  It was intended as a screen test for the band, to see how their musical charisma would translate into film. <P3-S2>  But the film was never officially released, due to the legal fights between the Rolling Stones and Allen Klein and a burglary in Andrew Loog Oldham's office, which saw all prints disappear. <P3-S3>  The footage was shot during the band's second tour of Ireland that year, on 3 and 4 September 1965, and was finished in the spring of 1966. <P3-S4>  It was given its premiere at the Mannheim Film Festival in October 1966.
