The late rapper Tupac Shakur was always astute enough to combine his lyrics with a groovesome backbeat, but it’s unlikely that even his musical ear was attuned enough to spot the potential of mixing ‘Thug 4 Life’ with the theme tune from Thomas the Tank Engine and Friends. Even if it was, Tupac’s untimely death meant the promise of such a farsighted vision remained unfulfilled.

Now, sixteen years on, some canny YouTube mash-up artists have brought the dream to life. So kick back with Henry G the Green Engine, Special Ed(ward) the Blue Engine but not – of course – Gordon the Notorious BIG Engine, as we visit the West Coast … of the Isle of Sodor. Peace out, Sir Topham.
