Well, those examples are creepy.
It's funny that this song came up in discussion because I was just listening to the 15 min album last weekend working out in the garden. Digressing: my mail carrier thinks I'm schizophrenic (HA! YOU'RE WELCOME, BRENDA!) because I listen to Neil Young one day, then Barry Manilow the next. And my mail carrier is NOT a Barry fan, as she has frequently pointed out to me whilst Mr M is serenading me as I'm pulling weeds. So, last weekend I'm listening to "Work the Room" and my mail carrier arrived. I said "Sorry for the Barry Manilow" and her response? "THAT'S Barry Manilow? That's a great song!"
Returning to topic: "Letter from a Fan", I've always enjoyed the counterpoint between the fan's descent into madness and the performer's own process of losing touch with reality: "I hear electricity; I know the size of the sky".
The performer's madness is a result of overwork and fatigue, living in a "Road Bubble", generally becoming alienated and being unable to relate to others in a normal way due to being a "superstar".
While the fan's madness is related to alienation and loneliness arising out of social misfit and/or mental illness. But, both performer and fan are struggling with their own isolation and loneliness. Neither can ever meet the other's needs, but both are dependent on the other. It's a brilliant song.
