In an effort to help his lover, Jeff Chavalier - who is described as a Canadian computer programmer, Browne and two of his associates at BP, set up a company called Txist.
Despite their obvious business talents, Txist Limited, appears to have collapsed after a year. There's no trace of a ringtone site of that name and Txist.com sells nutritional products.
The three shareholders in Txist were Browne, Dr David Allen - BP group managing director and chief of staff and Richard Balzer, Lord Browne's private adviser and a BP consultant.
Txist was chosen as an obscure reference to well-known French crooner, Maurice Chavalier's Txist du Canotier, apparently.
Seems Lord Browne and his chums put their heads together and decided ringtones should make them a few bob. ยต
