What was the tune that was playing as the mascot for West Brom went round the pitch at this years semi-final?

Before kick-off at this years FA cup semi final with Portsmouth V West Bromich Albion, the mascots for each team went round the pitch with a tune playing as they did so. I was very lucky to be there but for the life of me I cant remember how West Broms tune went and so I would be most gratefull for anyone who might know to answer. Thankyou.
