In page Billy Joel:

In late 1965,[citation needed] the Echoes changed their name briefly to the Emeralds, and then to the Lost Souls.[9] Joel left the band in 1967 to join the Hassles, a Long Island group that had signed with United Artists Records.[10] Over the next year and a half, they released four singles and two albums (The Hassles and Hour of the Wolf). However, all were commercial failures. Joel and drummer Jon Small left the Hassles in 1969 to form the duo Attila, releasing an eponymous debut album in July 1970. The duo disbanded the following October when Joel began an affair with Small's wife, Elizabeth. The pair later married.[11]
