So many, I've been into Abba all my life, hopefully I'll list a few here that haven't been mentioned yet.
My first favourite was Gimme Gimme Gimme, my mum would play it in the car on the way home from my drama lessons.
Chiquitita - would love dancing to the bit at the end in my room, also loved, The King has lost his Crown and Head over Heels.
My friend and I listened to one of her Abba tapes and hooted with laughter at the word 'Sex' in When all is said and Done, we were 11 at the time.
Another friend and I loved playing MarioCart when it first came out, (must be a while ago)we would play while listening to Tiger, singing 'I am behind you, I always find you, I am the Kooopaa'
We also danced to Dum Dum Diddle and Soldiers.
Listening to Move on helped me get through the end of my first relationship.
Other favourites are King Kong Song, What about Livingstone and Elaine is so fun and dancy. When I kissed the Teacher is slow but a good song.
Wish I could go to Voyage but I'm not in the UK.
