These Days by Bon Jovi: I got a couple of things wrong..and I sang it that way until I looked up the lyrics (I'm 20)
"These days the stars hang out of reach instead, These days there ain't a light up on the streets" instead of
"These days the stars seem out of reach, These days there ain't a ladder on these streets"
"his momma said he was crazy, he said: Momma I've got a child"..the right lyrics are
"momma I've got to try"
A childhood belief about misheard lyrics
