It will be nice to see again this band, but I really don't expect that much. Agnetha is 71, Frida is 75, and pretty sure their voices won't be the same. I really hope they will do at least a fine performance, though I'm afraid the risk of a shame is there. They wait too long to reunite.
And the magic is not there anymore. It was a pop group and pop groups have a specific moment in time. But if the new work is a piece of adult contemporary music, it will be welcome.
Abba Voyage will be released in November, before a "revolutionary" set of concerts where virtual avatars will play hits like Mamma Mia and Waterloo.
