Warner Bros. threatened legal action, forcing Zappa to shelve the release. Infuriated, Zappa hosted a broadcast on KROQ-FM in Pasadena, California, where he played the entire Läther album in sequence, repeatedly criticizing Warner Bros., and openly encouraging listeners to record the broadcast. Warner Bros. took further legal action against Zappa, which prevented him from issuing any material for over a year. During 1978 and 1979, Warner Bros. issued the disputed material over four albums – Zappa in New York (an edited and censored version of the original 1977 live double album), Studio Tan, Sleep Dirt and Orchestral Favorites. Zappa eventually won the rights to his Straight, Bizarre, DiscReet and Warner Bros. material, but remained trenchantly critical of his treatment by Warner Bros. for the rest of his life. Zappa's recordings were subsequently reissued on CD by Rykodisc (ironically it was later acquired by Warner Music), including Läther, which appeared posthumously in 1996. Ry Cooder was another Reprise act who was transferred to Warner Bros. in 1977. His first Warner release was the 1977 live album Showtime and he remained with the label until his contract expired in the late 1980s. His 1979 album Bop 'Til You Drop is notable as the first major-label rock album to be digitally recorded, and it became the best-selling album of his career. Thanks to its distribution deal with Curb Records, WBR scored the biggest hit single in the company's history in 1977. The ballad "You Light Up My Life" (written and produced by Joe Brooks) was originally recorded by the late Kasey Cisyk for the soundtrack to the film of the same name, in which actress Didi Conn lip-synched to Cisyk's recording. Teenager Debby Boone (daughter of actor-singer Pat Boone) was recruited to record a new version for single release, and this became a massive success, topping the Billboard Hot 100 for a record-setting 10 consecutive weeks, and earning a Platinum certification from the RIAA. It became the most successful single of the 1970s in the United States, setting what was then a new record for longest run at No. 1 in the US and surpassing Elvis Presley's "Hound Dog". Boone's success also earned her Grammy nominations for "Best Female Pop Vocal Performance " and "Record of the Year" and won her the 1977 Grammy for "Best New Artist" and the 1977 American Music Award for "Favorite Pop Single". The song also earned Joe
