Music Track - Abba

Now I've been very good, you must admit it, as I've only put ABBA on here once - one of the earliest posts in fact.  But back in the 70's they were huge in Europe.  This is one you don't hear too often http://www.youtube.com/watch?v=BWI2bTckbgc  Now I know that it's not fashionable to admit to enjoying ABBA, particularly in the US, but I've never used music as a fashion accessory.  It has to have three elements - Melody, Rhythm and Harmony.  This group never turned out a piece of music that lacked one of these, which is probably why they regularly used to post more annual sales than their Swedish business rivals - Volvo!
