I've just been reading Nigel Kennedy's tribute to Paul McGrath on the official site and he mentions he recorded a song in tribute to McGrath - "I Believe in God". I've just checked it out on Youtube and, you know what, it just could have the chops to be an entrance song. It's got a bit of a Led Zep "Kashmir" vibe and goes on for a good few minutes but the opening is good and atmospheric, it might sound the business in a full Villa Park.
