There is an idea which occasionally surfaces in the music world that whilst the possibilities in songwriting are supposedly endless, limitless and infinite, the great melodies and chord progressions have been used at some point already, and any hit - particularly of guitar-driven genres - will borrow from a predecessor.
This isn't necessarily to suggest plagiarism, certainly not always intentional borrowing from previous songs, but perhaps the melody which comes to a composer in a dream is not constructed in the unconscious mind, rather the emergence of a distant memory unfamiliar to the owner.
Ah, it's horrid. We all know it's horrid, from the board, to the designers, to the manufacturers, to the fans, to the innocent bystanders. As much as the club will claim a "Marmite factor", with as many people loving it as hating it, all good sense tells us it's a catastrophe. But, y'know, we've seen it.
For anyone who has no idea what I'm talking about, earlier this year, the amateur football club Windsor FC launched a new kit, to replace their earlier-released kit this season, and it features Union Flag (Union Jack) stylings, in the colours of the Italian Tricolore flag.
