I saw hazard in my local newsagent buying a twix so he's got at least 62p. probably more
Megalolz!!
Pendulum for sure. Chase & Status for sure. Roni Size? Perhaps at one time when he won the mercury prize for new forms but i doubt it any more. Kosheen smashed it for a couple of years so I reckon they must be pretty well off (Decoder & Substance). I doubt Andy C's a millionnaire, although his nightlife mix series must have brought in a fair few quid and he earns a lot for playing out. Baron's doing alright these days but he left the scene to write skateboarding video soundtracks and various other things so dunno if he counts really, he's done collabs with Snoop Dogg and all sorts.
