If it's the current one (I think!) with the lady advising people that she knows how they feel etc. - it's a song called 'Something Inside So Strong' which is by Labi Siffre and was a number four hit back in April 1987. If it's the previous ad - with the guy dydreaming about saving a girl from being crushed by a lorry, it's 'Search For The Hero' by M People, and that was a number six in June 1995. If they are running a new ad, please re-post, I don't see much TV, I'm too busy surfing The Answerbank!
