Abba!

6/9/79, Abba had their penultimate hit of their 70's run, with "Does Your Mother Know", from the "Voulez-Vous" album. This was the 11th of Abba's dozen (US) Top 40 hits in the last 6 years of the decade. What does it say that I have both the picture-sleeve 45 and the album???? I guess I just have a weakness for all things Sweedish! This song peaked at #19 on the charts.
