As he casually walks onto the stage with his bandmates, which include frequent collaborator and Gaslight touring member, guitarist Ian Perkins, it's a case of beaming smiles all round. The show opens with A Wonderful Life, the lead single from Painkillers, a song very much in keeping with his apparent outlook on things these days.
As was the case when we saw him on his first solo tour, each batch of songs is punctuated with Fallon sharing random thoughts, anecdotes, and a decent amount of two way conversation with the audience. Tonight someone calls him out for his pronunciation of "Adidas" when discussing how many pairs of trainers it's acceptable to own. This is the catalyst for an entertaining tale of how, whilst not ashamed to be American, he'd much rather be British. "You guys can beat us at everything. Yes, we've got Bob Dylan and Bruce Springsteen, but you have The Beatles and The Stones." He quips. The guy is clearly an Anglophile, going as far as to do a spot on impersonation of Noel Fielding's character Richmond from The IT Crowd at one point in the evening.
Such long gaps between songs might seem awkward, or leave you feeling short changed, with other artists, but tonight they seem to be an essential part of the show, adding to it rather than having any detrimental effect on the experience. Over the course of the one hour 45 minute set we still manage to get through 20 songs anyway, so you'd be hard pushed to complain.
