Rose M. Clooney was an American singer and actress. She came to prominence in the early 1950s with the song "Come On-a My House", which was followed by other pop numbers such as "Botch-a-Me", "Mambo Italiano", "Tenderly", "Half as Much", "Hey There", "This Ole House", and "Sway". She also had success as a jazz vocalist. Clooney's career languished in the 1960s, partly because of problems related to depression and drug addiction, but revived in 1977, when her White Christmas co-star Bing Crosby asked her to appear with him at a show marking his 50th anniversary in show business. She continued recording until her death in 2002.

"¿Quién será?" is a bolero-mambo song written by Mexican composers Luis Demetrio and Pablo Beltrán Ruiz. Beltrán recorded the song for the first time with his orchestra in 1953. Pedro Infante, for whom the song was written, recorded it in 1954.
