So long - Abba

Abba released four new picture disc 7" singles of the songs associated with their self-titled album from 1975. Abba was their third album, and the first single to be taken from that album was 'So Long', a rockier track than usual from the quartet. The single was released in most of Europe and in Australia and New Zealand in November 1974. Spain and Japan followed suit in early 1975. 

The B-side of this picture disc, 'I've been waiting for you' was actually also released as a single back in 1975, but only in Australia and New Zealand.
