In early 2005, McLachlan took part in a star-studded tsunami disaster relief telethon on NBC. On January 29 McLachlan was a headliner for a benefit concert in Vancouver along with other Canadian superstars such as Avril Lavigne and Bryan Adams. The show also featured a performance by the Sarah McLachlan Musical Outreach Choir &amp; Percussion Ensemble, a children's choir and percussion band from the aforementioned Vancouver outreach program. In addition to her own headliner show she also joined Delerium live on stage for their first-ever performance of "Silence". The concert was titled "One World: The Concert for Tsunami Relief", and raised approximately $3.6 million for several Canadian aid agencies working in south and southeast Asia. The show was the brainchild of McLachlan's manager, Terry McBride, CEO of Nettwerk. It ran for four hours and aired live on CTV across Canada.
