Courtesy of constant reader Nora Charles, I chanced across the photo below amidst a portfolio of publicity shots of Swedish dance bands of the 70s. That's The Claes Lennarth Club, who apparently were pretty hot stuff in the land of Ingmar Bergman and those wonderful meatballs at one time.
In any case, apart from proving that ABBA's fashion sense didn't occur in a vacuum, I was immediately struck by the uncanny resemblance between the band guy in the sweater in the middle (Claes Lennarth himself, one assumes) and legendarily dense TV film critic (I worked with him briefly, so I've got stories for another day) Jeffrey Lyons.
Jeffrey and a really interesting wig obviously had a second career going for themselves back in the day, and I can only say kudos and huzzahs.
In any case, if your heart can stand the strain, you can see more of the type of bands that passed for entertainment dans la terre du Sun de Minuit by clicking here.
