Sharon Osbourne urges fans to support Sarah McLachlan's music school fund

Sharon Osbourne has given singer Sarah Mclachlan's Christmas charity drive a welcome boost by urging her 1.3 million Twitter.com fans to give generously to benefit her music school.

The I Will Remember You hitmaker has been working to provide free music education programmes for underprivileged and at-risk kids through The Sarah McLachlan School of Music, and this season she is offering up a free festive tune recorded with the students of her school in exchange for fan donations.

And Osbourne has helped to raise awareness and spread the word about her pal's efforts by sending out a rallying call to her own Twitter.com followers on Thursday, asking them to support the cause.

She writes, "Help bring music programs to more children w/ (with) @SarahMcLachlan. Download her free song & give what you can to her charity".
