Andrew "Chowder" Charters used to play bass in j's band. I didn't really get the chance to talk to Chowder when he was still in the band, but an interesting point about him is that he used to be in the band Glueleg. For more on Glueleg, click here. This is a picture of Chowder, taken from the Glueleg website:
If i find out more about Chowder, i'll update this section :)
