Keep Holding On is a song originally sung by Avril Lavigne. The song was performed in every episode of Season One, Two, and New Generation except Glee-ality. The lead vocal was always sung by the person who had been eliminated that week, with the other contestants singing back up.
There's nothing you can say (Nothing you can say),
Nothing you can do (Nothing you can do)
There's no other way when it comes to the truth
(When it comes to the truth)
Keep holding on (holding on)
'Cause you know I'll make it through,
I'll make it through
