I may have completely misunderstood in which case I will be happy to be corrected.
Abba have written and recorded new music for the first time in decades. They won't be performing live instead avatars which will resemble their younger selves will be performing. No doubt it will be brilliantly done but would it really be so repulsive to watch people in their 70s perform pop songs?
Why can't the avatars resemble Agnetha and Annifrid as the 70 somethings they are now?
