If you dialled 123, you heard one of the BT Red Nose Climb celebrities that took over the Speaking Clock to help fundraise for Comic Relief (March 2009). You still got an accurate time check by one of the celebrities that were climbing Mount Kilimanjaro, including: Girls Aloud's Cheryl Cole and Kimberley Walsh, fellow popstar, Gary Barlow, Fearne Cotton and Chris Moyles.
BT donated 10 pence per call* from a BT fixed line in the UK that the Speaking Clock received during this fundraising period - raising more than £300,000. See www.bt.com/comicrelief
