MPL Communications – 1 Soho Square, London

Since the late 1950s, Soho’s been the unofficial clubhouse for London’s rising pop royalty—and nestled right in the heart of it is a little musical empire that just so happens to belong to Sir Paul McCartney. At 1 Soho Square, behind the charming Georgian façade, sits MPL Communications, Paul’s music publishing company since 1970. Yes, the man doesn’t just write hits—he owns them too. In fact, Macca’s the world’s largest independent song publisher, with over 3,000 songs under his belt, including the Buddy Holly catalog and more Broadway gold than a Tony Awards afterparty.

Now, Sir Paul’s not crunching numbers himself—he’s got accountants for that. But he still keeps an eye on the creative side, because why just rest on your Beatles laurels when you can run a mini-musical kingdom?

Oh, and here’s a fun twist—beneath this historic building lies a secret weapon: a fully decked-out recording studio, a faithful replica of EMI’s legendary Studio No. 2. No public access, of course—but if you happen to be loitering respectfully nearby, you just might catch a glimpse of Macca coming or going. He’s famously unpredictable: one day a ghost, the next, he's waving at tourists like it’s Abbey Road all over again.

And if you’re strolling by after dark and the curtains are drawn just right, look up—you’ll see his office glowing with the reflected shimmer of wall-to-wall gold and platinum records. It’s not a museum, but it’s the closest thing to one this side of Penny Lane.
