It's just sad sometimes when the old band gets back together for one more show, maybe to pay off some mortgages or help a grandchild through grad school. Various original members are dead or too demented to perform. The ones who do show up have to review recordings of the old material to relearn it. Really, it's like seeing a tribute band composed of retirees. Especially since, like infants, old people tend to look alike. Is that really Mick Jagger, or just Don Knotts in a Beatle wig? Of course, at a certain age Funny Walks are pretty much spontaneous.
