Björn told Smooth Radio: "It was a global reaction which was fantastic! We never expected it, but we just put it out because we thought the news would get out and there'd be rumours about a reunion and stuff.
"So we put out that just to make people aware there were these two new songs in the can and we thought we'd be able to release them much sooner."
However, ABBA fans will have to wait a bit longer, with Björn confirming: "Because of technical difficulties in creating the digital copies of ourselves that are going to sing these songs, it won't be until next year."
"Then Benny and I thought, 'These ABBAtars, for want of a better word, shouldn't they have something new to sing as well? Well, yes!' So we wrote a couple of new songs, we called the ladies and they said, 'Yeah, great! Let's meet in the studio and see if we still can sing! If it sounds bad, we won't release it, we'll just have fun in the studio'."
This is the first time ABBA have all been back in the studio together in almost 36 years, but Björn noted the band felt at home within seconds.
Björn continued: "Oh yes, it just took virtually seconds. We were standing in front of one of those sound desks in the control room, the four of us, and we were just kind of looking at each other.
For all you Jason Isbell fans out there, he just released a bunch of live shows for download and streaming, and promises that there's more to come. Enjoy!
