contestants forgettign lines

Did anyone notice that in the elimination round many contestants messed up with a line or two.

like Joy jus murmered sth rather than a whole line..even junaid forgot a line n repeated teh earlier line twice..n then Raja, but joy n junaid kept on going n didn't stop but Raja stopped tht's why it was more visible in his performance.

i think it's all coz of the stress of elminiation round.
