TLC (or some other R&B gal-group) had a hit a couple of years ago with a song titled "Waterfalls" that featured the same "Don't go chasing waterfalls" lyric (and similar vocal phrasing).  This may be a dumb question, but what the hell....  Was that (a) a common phrase that I just never heard until McCartney II came out, (b) a subtle rip-off that nobody cared much about, or (c) coincidence?
