This needs a bit of work. At the moment it reads like it was written by fans. For example: 

"Bassist Bruce Foxton made up for the group’s lack of a second guitarist by carrying much of the melody in his distinctive playing, a confluence of the power of John Entwistle with the speed and melodicism of Paul McCartney. His instantly memorable basslines were the foundation of many of the group’s songs..."

Now, I liked The Jam, so I would slightly tent to agree with that statement. But we aren't supposed to be stating our own opinions here. We would need a quote or a ref from a verifiable souce. That's just one example. I'll see what I can do myself too of course.
