At the beginning of "Lady", JY is back at his keyboard. Lawrence plays the "piano" sounding part at the beginning of this song, and JY plays the "synthesizer" sounding part. JY and Todd grin at each other at the beginning and JY taps an invisible bell with his finger as Todd hits the real one - ding! - at the beginning of each line.
I think Lawrence does a great job on this song, and you have to see him! He comes out from behind the keyboard for this one and is all over the stage. The arrangement they do of this song on this tour seems to make it a much harder song, and they all really get into it. As soon as JY and Lawrence leave the keyboards after the first verse of this song, it is no longer a gentle ballad!
