Wikipedia:Articles for deletion/Third Party (British DJs)
managed to find a single third party source, but it's in the http://www.liverpoolecho.co.uk/whats-on/music-nightlife-news/size-records-stars-third-party-10440249 Liverpool Echo, a locally distributed paper with no national coverage. Clearly no 'widespread' coverage and no charting singles or albums - as such fails
