Well Joe *did* perform last again, and he *did* have a far better song to sing than Olly (Don't Stop Believing > Twist and Shout, ffs). I wouldn't be suprised if Simon "strongly advised" Olly to go for TAS actually. Plus the winners song suited Joe alot more than it did Olly, and Joe's celebrity duet partner got to perform his new single (just like Beyonce and Kylie Minogue after they performed with Alexandra and Leon

giving Joe a possible advantage.
The judges comments were very telling as well, with Louis saying Joe had the edge over Olly and Cheryl bursting into tears and Dannii saying last night that she wanted Joe and Stacey in the final two. Simon gave Joe alot more praise than Olly.
I liked Joe but there's no denying he didn't get some special treatment tonight.
