A daring tribute to cross-generational flirting in big city nightclubs. Like 'Voulez-Vous', 'Does Your Mother Know' was a disco track when it was released, but on 6th February it was more of a boogie-rock stomper, and a full 30 seconds longer with an introduction building up with drums, bass, piano, and then guitar. "We had seen Rod Stewart in concert in Leicester in December" remembers Ola Bunkert, "and his drummer Carmine Appice did some drumming which I thought was kind of cool. When we were to record 'Does Your Mother Know', Benny asked me to do some solo drum bars for the intro, and then I remembered what Appice had done, and sort of copied that. I liked the fact that the song would start with drums only, because that was a bit unusual for ABBA and I was a bit disappointed when they eventually cut that from the track." Also several attemps were made to record the song with Agnetha and Frida on lead vocals instead of Björn. "I thought the song was a potential hit , and we really were a bit reluctant to have me as the lead vocalist on a single, says Björn. "For song reason, I sang it anyway, and I think that was a big mistake. The recording would have benefitted from focussing more on the girls' voices."
