Doubt it however what is clear is that this group of men has grown into this relationship that may have had some rocky roads. However, the boys have always maintained the golden rule; keep your dirty laundry in house. You never see websites, gossip sites posting issues with the band, management or frankly anything thing that would cause "shade" on the band.
They fully understand that they have an image, a product that has taken years to grow into a mega giant and at this stage of their musical careers, it's more important to remain true the concepts of music, relationships and of course you the fan.
What does the next 40 hold for U2 well, we all know that old rockers just fade away they never die. Heck Rolling Stones are heading out on tour summer of 2017, and those boys are in their 70's could we expect to see U2 hitting the road at 70? One would never know.
However, one thing is for sure. Faith, Hope, and Love have kept this band together this long and while tomorrow never promised we could put some confidence in the possibilities of the lyric being true. "I'll be with you again."
