Who were the original members and what did they play? 

I am unable to be sure who the original members of the band were, how many they were, and what instruments they playe. Even sifting through the opening section leaves me with some uncertainty, although para 2 tells me the original drummer. I know this is a voluntary project, and I'm grateful for there being any info at at all. Nonetheless, after reading the first paragraph I'm unable to answer basic questions like this.

The opening says: "The Jesus and Mary Chain originally revolved around the songwriting partnership of its two main members, plus third founding member, bass player Douglas Hart. In the early days, Reid's guitar would be left out of tune, while Hart's bass guitar only had two strings"

Who were those two main members? What did they play? One Reid (which one?) plays guitar ... does the other play guitar too? Two main members plus third found member - this implies to me that it was a 3 piece band. Was it? Was the original drummer mentioned in para 2 the other "main member"?

I'm sorry, but I'm annoyed by articles like this, which seem to assume some starting knowledge on the part of readers and don't specify exact information.
