Save your kisses for me / Fernando

So who performed these two cover versions? There's no information on the sleeve or label. All we know is that this single was released in Portugal and there's a decidedly seductive sleeve on this one.

'Save Your Kisses For Me' is, of course, a cover version of Brotherhood Of Man's winning Eurovision song from 1976, whereas 'Fernando' was originally recorded by Abba in the same year (and by Frida from that band a year earlier). The Eurovision cover sounds a lot like the original, the other one... well, not so much. Still, it is an interesting rarity that I ordered together with two Portuguese Eurovision songs.
