It is too long, but it's actually justified. In the old ITV version, the logo would form up as the main part of the song ends, and the ending of the tune would be when the presenters come out. The song seems to have actually been extended as there's an instrumental part and then the first line of the lyrics plays again before you get the ending bit with the logo. Presumably, the extended theme, along with the WWE style Gladiator intros, serves to fill some of the space created by not having commercial breaks.
