As Henry Mancini was signed to RCA Victor, that company handled the soundtracks of the United Artists films that he composed the music for, most notably "The Pink Panther"; exceptions include "Gaily, Gaily", "The Hawaiians", "The Pink Panther Strikes Again" and "Revenge of the Pink Panther". Many of these soundtracks have reverted to Metro-Goldwyn-Mayer, whose MGM Music unit licensed them to other labels for reissue, first Rykodisc, then Universal Music and EMI. As owner of Columbia and RCA Victor, Sony released the "West Side Story" original cast album and film soundtrack on CD. Sony has owned most of Mancini's soundtrack albums since its music division's merger with BMG in 2004.
