Yes, I searched, and I'm frankly surprised this didn't turn up.
As I was Concordancing this evening, I came across this passage:
Of course, curiosity killed the cat, and even if satisfaction supposedly brought it back, there's still that little problem with the man on the radio telling me more and more about some useless information. But I didn't care. I just turned the radio off. (xviii)
Yes: we get a snippet from the first verse of "(I Can't Get No) Satisfaction" by the Rolling Stones. But what is even more interesting, given this point in Johnny's account of his growing involvement with TNR, is the line in the song that immediately follows what is quoted here, and which Johnny (conveniently?) leaves out: "Supposed to fire my imagination." Johnny's imagination by this time is more than stoked, so no wonder what he hears is "useless" to him. And more: his turning the radio off is his first gesture in the direction of isolating himself from others.
So, then: has anyone else noticed quotes from songs in HoL? What/where are they? And what do you think their connection(s) to the text might be?
