"You take the plane, I'll take the bus this time"

A British firm has bought the company that operates Greyhound buses, which is some kind of payback for the number of Premier League clubs that are being snapped up by Americans. I've never actually been on one, but thanks to the closing scenes of "Midnight Cowboy", Paul Simon's "America", Jonathan Richman's brilliant "You're Crazy For Taking The Bus" and innumerable other references to them in music, movies and books, I feel as if I have. Was it cheap flights that did for them?
