The Beatles, “Dig a Pony” – 1.30.69
Let’s just say, you’re given any time and any space and any band and any concert and the power to be right there, in the thick of it. You could pick Beatles at Shea (though no one could hear them) or Cheap Trick at Budokan, or Woodstock or The Rolling Stones at Altamont, or any other obvious choice for “concert you wish you’d have been at.”
Me, I’d go a completely and totally obvious route. Especially after watching this, one of my favorite songs. Dig it, right?
