I agree with J Turows about "It began with a pint..." lead in - the emphasis on story was a key piece of advice from Jeff, Katherine, and Lucy. The "Once upon a time" device makes it very clear what we're getting here is story, that there's a story to be told, and only very interesting things deserve a tale / myth to be told.
However, I find the switch to present tense a bit clumsy. I think either keep it all present, "We open on two friends sharing a pint..." or switch to past "It began with a pint... The year was 2005, and neither Jamie Floyd..." etc. Just something to have the story flow naturally from the first compelling line
