Er, I'd have to go and check Muppet Wiki for Episodes 3786-3790 to find out if there were Elmo's World episodes attached when the five-part Hurricane on Sesame originally aired. But since that was in Season 32, my guess is most likely that they did. But as was said in the thread for the special airing SW edited the five episodes so they'd be condensed into a full-hour viewing, so I'd think they would have gotten through it without any Elmo's World.
And even if they had decided to include the Elmo's segment at the end of today's airing, it would have been an Elmo: The Musical, cause you know how they have to retrofit older episodes into the current format.
