Did they postpone their UTABAN appearance in the last minute or something? I could've sworn the schedule said "5/31 TBSテレビ系 「うたばん」 19:54～20:54" at the official SPEED website.
I was quite shocked because I watched the full 2009/05/31 episode today, and they weren't there. On top of that, there was also only one live performance ("Ashita no Kioku" by ARASHI). There are usually at least two every week.
Both UTABAN and SPEED official web sites now confirms that they will be there on 6/7 though.
Looking forward to yet another "S.P.D." performance.
