The 1980 single release of "Sleepy-Time-Toy" led to a disagreement within Baccara over the vocal mix used. Mendiola complained that her voice was not given sufficient prominence in the song's arrangement and sued RCA for breach of contract. Mendiola's case was that the song should not have been released as a Baccara recording when it amounted to a Mateos solo. A court hearing in Munich resulted in 250,000 records being recalled from dealers and a revised recording with a new vocal mix being issued in place of the original. A 28 second instrumental bridge was removed from the start of the recording (thereby reducing the play time from 6:12 to 5:44) and the vocals were remixed so as to give Mendiola and Mateos equal prominence. The artwork for the single's cover appears to have remained unchanged. The single failed to chart successfully (see Discography below).
