 Dave Simpson of The Guardian described the opening of the show during his review : " Some while after Beyoncé is due on stage , a voice announces that the support act won 't be appearing and that Beyoncé will be with us ' in a moment ' . Like everything else – hits , boots , hair and sponsorship deals – moments are very big in Beyoncé world . An age later , cheers erupt for the raising of a curtain which revealed , er , a <unk> <unk> with a drum kit . An hour later , the <unk> music is getting gradually louder to drown boos and the cries of small children whose parents are moaning it 's getting past their <unk> . " The show opens with " Baby Boy " which Beyoncé sang while being lowered onto the stage upside down . A highlight for many fans was her performance of " Dangerously in Love 2 " . During the tour , a special 8 @-@ minutes rendition of the song was performed .
