When Ian Anderson (Jethro Tull) was questioned why he didn't go after The Eagles for their big hit "Hotel California" he said:
"It's difficult to find a chord sequence that hasn't been used, and hasn't been the focus of lots of pieces of music. It's harmonic progression is almost a mathematical certainty you're gonna crop up with the same thing sooner or later if you sit strumming a few chords on a guitar. There's certainly no bitterness or any sense of plagiarism attached to my view on it, although I do sometimes allude, in a joking way, to accepting it as a kind of tribute."
