My first is in The Booth but not in The Chair. My second is in Red Rum and also Corbiere. My third is in Canal Turn but not Melling Road. My fourth is in the Bob Champion But not in the horse he rode. My fifth I in the one who beat Devon Loch and twice it appears in St Valentines Brook. My last is in Hedgehunter but not in Final Ben. He man you seek is an Aintree legend
