Move over Jim McGrath. Step aside Sir Peter O'Sullevan. For the BBC's final Grand National before the race moves to pastures new at Channel 4, Top Gear top boy James May is providing an alternative commentary, which will be available via the TV remote control red button. The stunt is part of a challenge he has undertaken for the new series of James May's Man Lab. In the show he attempts to encourage people to brush up on old skills. For the challenge James has been given tips on how to memorise the horses and jockeys using word association and other memory tricks. Monkey is sure, with all those Top Gear run-ins with editorial policy over situations such as drinking gin and tonics while driving to the magnetic north pole, James will have no trouble remembering the name of Irish 12-year-old In Compliance – something the Top Gear production team is rather familiar with.
