Agnetha (in 1977) and Frida (in 1979) on stage. Nervous Agnetha never too keen on performing in front of a boiling audience while Frida simply and clearly loves the stage.
ABBA after winning Melodifestivalen (or right before...) in February 1974. Bjorn looks like he is missing a tooth (click and check the bigger sized pic) and luckily at least Frida notices this photographer.
Not sure what is going on here but Agnetha and especially Benny do not look too pleased while Bjorn and especially Frida are all smiles... lol! Here we have ABBA on the road in 1974.
Ring Ring... Benny, Bjorn, Frida and Agnetha in a well known happy clappy mood posing for a pic that would end up on the Ring Ring single (as seen here from Brazil and Denmark) in 1973. (Single sleeves from http://www.abba4therecord.com)
