This will be a huge? hit if it happens, or maybe just a hit.
I didn't see the vid, but for me, I'd like to see ted being the responsible adult, ie, married, with kids, a 9to5 job etc, he's all serious now.
Bill on the other hand is the same ole bill. Odd jobs, jumping from band to band, partying, etc.
B&T had a breakup over something stupid and haven't seen or spoken to each other in over 20 years.
Another time traveler from the future visits bill and tells him things haven't changed for the good yet, and in fact, they are getting worse.
The future she knew is disappearing.
She barely had time to make a time jump and it will be the last one she can make. It was random and she couldn't control when she would visit their lifetimes, and that bill must somehow find the "old" ted in the new, more serious ted.
( if any of "that" old Ted is even left )
She disappears from the timeline right before Bill's eyes.
Who was The time traveler? ellen degeneres.
Bill will have to find a way to convince and "retrain" ted or all is lost.
The song must be written.
