Whatever happens in our band, the agreement is if one of us can`t do the gig for whatever reason, the band don`t play. There are enough bands on the scene that could be asked to stand in, so that people get a whole rehearsed line up, rather than a probably hastily put together line up that are more than likely to not play as well. Whilst I`m sure many bassists could play what I do (it really isn`t that difficult, trust me) not many play the way I do, or get the same sound, be that by eq or by style. Same with the drums, our drummer has a style that I`ve really not heard before, it fits our music but someone without his drums, well it would take a great deal away. And guitarist/singer - well it`s all about the guitarist/singer in most bands isn`t it, and ours is no different, we couldn`t gig without him.
