BBC News - Bjorn I am reminded of Abba every day 

Sorry Bjorn. The reason for your success is simple: You and Benny writing incredible songs and Frida and Agnetha's voices. That is why we all listened. Thank you for the music!

The reason they were so successful? So many reasons. It was like lightning in a bottle. Two friends who are geniuses at writing music meet and fall in love with two incredibly talented singers, who also just happen to have voices that blend perfectly together. There wasn't a dud in the group. They each brought something magical that if one were missing it would not be the same. They've all had success after the breakup, but nothing was quite as good as when they were together. The women were both beautiful, one a fiery passionate redhead and the other a mysterious and aloof Swedish blonde, the costumes were outrageous and pure 70s camp. It all just worked. Then when the breakups happened, it added a maturity to the group that took them well beyond a mere pop group... and their later music is now recognized as being incredibly crafted and poignant. There will never be another group quite like ABBA.

No other group in the world was ever offered $1billion dollars to reform and tour. That's got to say something about their brilliance.

No pretence, no arrogance. Just pure talent and lovely personalities. That's ABBA!

Björn, sir, you said you didn’t know what was the secret of your success, however you mentioned it: “we did it from my hearts.” And that was the secret.

It came from their hearts... and their amazing talents, voices. Plus it’s true, what Frida has said, they were all in love. The power of love ❤️

The secret was Frida and Agnetha singing in harmony. That is the ABBA “sound” we all think of first. Two great voices, complementing each other perfectly.

To everyone here saying that Frida looks better here......what are you trying to say? Frida was absolutely gorgeous in her younger years, just as she is now!

Frida is aging beautifully!!!

I absolutely have loved ABBA since they started. All my friends mocked in the late 70s. But in a friendly way. Agnetha Faltsog was one of the most beautiful women I have ever seen and very modest. She still exudes natural beauty to this day.

Frida is beautiful, i love her voice

Frida was correct in what she said about ABBA's success; and I love her accent and smile.

Two girls and two guys came together to create sheer magic that will be unrivaled ever again

I love them both frida has ages so beautifully her voice is so very special it can reduce me to tears

She’s aged so well.

Frida is a very lovely woman. Dare I say more now than ever. Thanks for the memories!

Bjorn and frida seem to really get on

such humility from Frida and Bjorn. They are down to earth people but are incredibly gifted in music. We love you ABBA!

Divna Frida!!

They are just lovely gentle people , I love them forever and Frida ssmile is so 🙂🙂 nice xx
