Question: Alex Orbison and Roy Orbison Jr are co-presidents of which publishing company?
Context: Alexander "Orbi" Orbison (born May 25, 1975), also known as Orbi, is an American drummer, writer, director, and film producer.  Alex is president of Still Working Music Group, a publishing company and president and co-founder of Roy's Boys LLC, through which Roy Orbison's legacy is managed alongside his brothers, Roy Jr., and Wesley Orbison. Roy Orbison at the Rock House is the first album by Roy Orbison.  It was released in 1961 by Sun Records at a time when Orbison had already moved to the Monument label but had not yet put out an album.  Sun Records owner Sam Phillips had a collection of songs Orbison had recorded at Sun between 1956 and '58.  Phillips capitalized on the national recognition Orbison had achieved at Monument through three major hit singles in 1960 and '61 that had gone to the top of the Billboard charts. The Roy Orbison/The Beatles Tour was a 1963 concert tour of the United Kingdom by Roy Orbison and the Beatles.  Other acts on the tour included Gerry and the Pacemakers, David Macbeth, Louise Cordet, Tony Marsh, Terry Young Six, Erkey Grant, and Ian Crawford.  It was Orbison's first, and the Beatles' third nationwide tour of the UK.  Although Orbison was originally intended to be the headlining act, the reaction to the Beatles on the tour caused them to be promoted to co-headliners, with the Beatles closing the set in the traditional headlining spot. Roy Orbison's Many Moods, also known as The Many Moods of Roy Orbison, is the thirteenth album recorded by Roy Orbison, and his seventh for MGM Records, released in May 1969.  It included two singles, both of which were minor hits in the UK; "Heartache", which just missed the Top Forty, stalling at #44, and "Walk On", which scraped into the same chart, stopping at #39. Whitestarr is an American rock band from Malibu, California.  The band has garnered attention owing to the members' relationships and to their television series.  Lead singer Cisco Adler is the son of well-known music producer Lou Adler and drummer Alex Orbison is the son of music legend Roy Orbison. "You Got It" is a song from Roy Orbison's album, "Mystery Girl" (1989).  The song reached No. 9 on the "Billboard" Hot 100 and No. 1 on the adult contemporary chart, returning Orbison to the Top 10 for the first time in 25 years.  It also reached No. 3 on the UK Singles Chart in early 1989, posthumously released after Orbison's death of a heart attack on December 6, 1988.  While "You Got It" was Orbison's last hit single in the U.S., the single "I Drove All Night" made No. 7 on the UK charts in 1992.  In addition, it was his only solo Top 10 hit on the Hot Country Songs charts, peaking at #7.  Although it is an Orbison solo single, Orbison's fellow Traveling Wilburys bandmates, Tom Petty and Jeff Lynne, co-wrote the song and played instruments on the record. "Oh, Pretty Woman" is a song recorded by Roy Orbison, written by Orbison and Bill Dees.  It was released as a single in August 1964 on Monument Records and spent three weeks at number one on the "Billboard" Hot 100 on September 26, 1964 - the second single by Orbison to top the US charts.  It was also Orbison's third single to top the UK Singles Chart (for a total of three weeks).  The record ultimately sold seven million copies and marked the high point in Orbison's career.  Within months of its release, in October 1964, the single was certified gold by the RIAA.  At the year's end, "Billboard" ranked it the number four song of 1964. Roy Orbison's Sun Recordings were made by Roy Orbison at Sun Studio with producer Sam Phillips.  Sun Records was established in 1952 in Memphis, Tennessee, and during an eight-year period Sun Records signed such artists as Roy Orbison, B.B. King, Howlin' Wolf, Ike Turner, Rufus Thomas, Elvis Presley, Johnny Cash, Jerry Lee Lewis, Carl Perkins, Harold Jenkins, and Charlie Rich.  The musicians signed at Sun Records made music that laid the foundation of rock and roll in the 20th century. Early Orbison is an album recorded by Roy Orbison on the Monument Records label at their studios in Hendersonville, Tennessee and released in 1964.  Essentially a compilation of songs from his first two Monument albums, it is most noteworthy for containing "Pretty One", the "B" side of Orbison's second Monument single, "Uptown".  Many Orbison fans believe "Pretty One" would have been his first major hit had it been promoted as an "A" side.  The second song of interest on this album is "Come Back to Me My Love" which Fred Foster, owner of Monument Records and producer of all of Orbison's earliest hits, says was the song which inspired production of the hit arrangement that later became "Only the Lonely". Roy Orbison Jr. is an American musician and record producer.  He is also the cofounder of the record label Roy’s Boys, and co-president of Still Working Music.  Among his work, he co-produced the album "Roy Orbison: The Ultimate Collection", which reached #10 on the UK Album charts.
