Denise Marsa is an American singer/songwriter, born in Trenton, New Jersey, United States.
When performing in a club she was approached by Dean Friedman, who invited her to sing on his next album.
She sang a duet - "Lucky Stars" - with Friedman, on his second album "Well, Well", Said The Rocking Chair.
3 in the UK Singles Chart in late 1978[2] and number 6 in Australia in early 1979[3] Marsa also sang backing vocals on several other songs on the album.
Because the record company did not publicize her name on the single, she was known as the "mystery voice" for some months.
