A Delhi musician has completed a record-breaking public performance in which he played the violin non-stop for 50 hours.  Paras Mani Choudhary's marathon recital was certified by officials from the Limca Book of Records, an Indian-based records book. The previous record was a mere 32 hours. Choudhary was already in the Limca Book of Records for playing the sitar for a world-record 92 hours two years ago.
