The unofficial Inspector Spacetime Wiki Madman with a Booth has now reached its 300th article! First inspired by Community's "Biology 101" and based on the expanded fanmade canon from TV Tropes, it's been affectionately parodying "That Ripoff" since September 2011.
The Fifteenth Inspector and Lucy Skye meet The Rutles in 1960 but discover that the The Bandmaster and his crew of Radio Pirates are changing history to displace the "Pre-Fab Four" from their position as the most influential band of all time. Instead, the Bandmaster is promoting a little-known Liverpudlian group called The Quarrymen.
The Inspector takes Dirk, Ron, Stig, and Barry on a "Tragical History Tour" in the BOOTH to see how their music will change the future. This gives them the opportunity to plagiarise themselves, and they return with their notebooks full of hits. The departing Inspector calls The Rutles' story, "A living legend, a legend that will live long after lots of other living legends have died."
