This one made no impression on the charts, at least in the UK, though it's an excellent song. It was only when Mamma Mia was released later in 1975 that Abba really arrived.
Surprisingly, only 4 ABBA singles made the top 10 in the USA. This one topped at 15. Mamma Mia barely cracked the top 40. I remember them better than that, probably because I had a best-of record. Ring Ring didn't chart at all, but I remember it.
