A guitar signed for charity by rock legends Eric Clapton, Brian May, Jimmy Page and Mark Knopfler has been lost in the post. The autographed Fender Stratocaster was set to fetch $40,000 (GBP20,000) at auction to raise cash for a children's hospice, but in a catastrophic mix-up it vanished after being posted from London to Leicestershire, England. The mail company responsible, Parcelforce, has agreed to give $30,000 (GBP15,000) to Rainbows, the charity concerned.
