Robbie, one third of the legendary Images of Mathematicians on Postage Stamps, rips a guitar from Pete Green and in front of a packed crowd of five people sets out on his band's fifth gig.
Admittedly he can only remember one song, but its a classic, Tim Berners-Lee and the Dream of Spiders. For over a year just a name on Last.Fm before he wrote it. Named in the vein of Judy and the Dream of horses, it tells of how the world wide web revolutionised geekdom and meeting people.
Caroline points out that all the crowd and the band are Bowlies, I back away and frown to myself. Gazing into the distance, its a green and yellow land here. There's a wee carriage decked out as a railway memorabilia shop so I buy myself a British Rail traion drivers jacket with brass buttons for £2.
More people arrive to hear Robbie half remember songs, having listened to them on Caroline's iPod.
Santa Always Brings me the Blues, almost drowned out by short hipster girls chatting. Its a Christmas song, but it does refer to Central Station so its kind of a train song.
Robbie's going to have to sing louder to make it as a troubador.
