Okkerville River’s Will Sheff is absolutely in love with an obscure German TV concert tape of Dr Hook & the Medicine Show (conveniently also on YouTube; he embeds bits to illustrate his points) and has written a truly remarkable analysis of it that is absolutely worth your time even if you’re only vaguely aware of who this band was. It is in particular compelling in its insight into the musical and interpersonal dynamics going on in a live performance, which I find fascinating.
When you’re done, check the comments. It turns out two members of the band show up there and weigh in, which is awesome (frontman Dennis Loccorriere, and guitarist Rik Elswit).
