British singer Gary Barlow has hit the road in a pink Rolls-Royce to drive the length of the U.K. in a bid to raise $1.6 million (£1 million) for charity. The Take That star is behind the wheel of the 'Fab1' vehicle, modelled on Lady Penelope's pink car in classic puppet show Thunderbirds, which he will help drive from the most southwestward tip of the U.K. - Land's End in Cornwall, England - to the most northerly point of mainland Scotland, John O'Groats. The road trip, dubbed the FAB1 Million challenge, began on Thursday (18Apr13) and aims to raise $1.6 million (£1 million) for Breast Cancer Care. Barlow will be joined by D:Ream rocker-turned-scientist Professor Brian Cox, TV/radio presenter Chris Evans and Top Gear co-host James May. The trip is expected to take around 16 hours to complete.
