In 1971, he collaborated with Linda and drummer Denny Seiwell on a second album, Ram. A UK number one and a US top five, Ram included the co-written US number-one hit single "Uncle Albert/Admiral Halsey". Later that year, ex-Moody Blues guitarist Denny Laine joined the McCartneys and Seiwell to form the band Wings. McCartney had this to say on the groups's formation: "Wings were always a difficult idea ... any group having to follow [the Beatles'] success would have a hard job ... I found myself in that very position. However, it was a choice between going on or finishing, and I loved music too much to think of stopping." In September 1971, the McCartneys' daughter Stella was born, named in honour of Linda's grandmothers, both of whom were named Stella.
