In November 2003, ten months after Maurice's death, Gibb produced and contributed background vocals and guitar to two songs performed by Cliff Richard, "I Cannot Give You My Love" and "How Many Sleeps?"; Maurice's keyboard work from a 2001 demo version was included in this 2003 version. On 2 May 2004, Barry and Robin Gibb received the CBE award at Buckingham Palace; their nephew Adam accepted his father Maurice's posthumous award. Also in 2004, Gibb co-wrote and sang background vocals on his son Steve Gibb's solo single "Living in the Rain". In January 2005, along with many artists, Gibb and his brother Robin recorded vocal parts for the charity single "Grief Never Grows Old" on behalf of victims of the tsunami in the Indian Ocean on 26 December 2004. In April and May 2005, Barbra Streisand recorded songs for her new album produced by Gibb. In August 2006, two Gibb singles, "Doctor Mann" and "Underworld", were released on iTunes. "Underworld" was featured on the film soundtrack of "Arctic Tale" but not in the film. On 7 December 2006, Gibb joined 4,500 other musicians in a full-page advertisement in the "Financial Times" newspaper, calling for the British Government to extend the existing 50-year copyright protection of sound recordings in the United Kingdom. The fair play for musicians advertisement proposed that the copyright be extended to the American standard of 95 years and was a direct response to the Gowers Review (published by the British Government on 6 December 2006), which recommended the retention of the 50-year protection for sound recordings.
