When I lived in Upper Holloway a few years ago I regularly travelled on the #41 bus. It was not uncommon for a group of local lads to occupy the back seats on the upper deck and turn on their boombox, usually playing Hip Hop at high volume (far better, sometimes on a Ladbroke Grove bus you'd get some high quality Dub). There was also a regular passenger on the #41, an elderly Jamaican woman, who would stand at the bottom of the stairs and bellow some highly original versions of well-known hymns, all of which seemed to end with "I know 'cos Jesus loves me".
