LYRICS:I know I took the path that you would never want for meI know I let you down, didn't I?So many sleepless nights where you were waiting up on meWell I'm just a slave unto the nightNow remember when I told you that's the last you'll see of meRemember when I broke you down to tearsI know I took the path that you would never want for meI gave you hell through all the yearsSo I, I bet my life, I bet my lifeI bet my life on youI, I bet my life, I bet my lifeI bet my life on youI've been around the world and never in my wildest dreamsWould I come running home to youI've told a million lies but now I tell a single truthThere's you in everything I doNow remember when I told you that's the last you'll see of meRemember when I broke you down to tearsI know I took the path that you would never want for meI gave you hell through all the yearsSo I, I bet my life, I bet my lifeI bet my life on youI, I bet my life, I bet my lifeI bet my life on youDon't tell me that I'm wrongI've walked that road beforeAnd left you on your ownAnd please believe them when they sayThat it's left for yesterdayAnd the records that I've playedPlease forgive me for all I've doneSo I, I bet my life, I bet my lifeI bet my life on youI, I bet my life, I bet my lifeI bet my life on youSo I, I bet my life, I bet my lifeI bet my life on youI, I bet my life, I bet my lifeI bet my life on you?

If I have to describe it in my point of view, the "demons" he is referring to are the bad/sad memories that make people feel different towards other people, and life altogether. You see the people who are zoomed into aren't cheering in this concert, meaning they aren't screaming in praise, but they relate to the song on a much more deeper level. Where these bad/sad memories make them look negative or whatever. But the real "demons" are these bad/sad memories that are inside them. Including the singer's own sad memory of tyler who died in 2013.
