[2] Initially performing under the name Peter Ranking, he changed his name when he discovered that another deejay was using that name, and since he was resident deejay on the Metromedia sound system, he chose the name Peter Metro.
[2] His use of Spanish gained him many fans in South America, and he is acknowledged as the first multilingual reggae toaster.
He appeared at the Reggae Sunsplash festival in 1987 with English deejay Dominic, captured on the Reggae Sunsplash Dancehall X '87 video.
He performed the song "The Can" and "Don't Give Me That", the latter one being an anti-cocaine statement which made reference to Richard Pryor's mishap with crack in 1980.
Metro contributed ‘Oh No Baby Don’t Go’ to The Dance Hall Album (1998) when UB40 invited guests to produce their own versions of songs from the backing tracks of their 1997 album ‘Guns in the Ghetto’.
