Armed with an accordion and wearing a fetching chocolate brown pork pie hat, musician Jason Webley is here. Or as he puts it, an “unknown hairy guy who plays the accordion” is here. Having navigated some technical difficulties, Webley brings the audience firmly on side with his self-deprecating humor and folksy blend of charming cod philosophy. With one song both named in honor of the title of the session and calling for audience interactivity, it’s quite something to behold the assembled crowd throwing up their hands to the roof to yell, “Why?” Credit to them, they did it with gusto.
