“You let the people see
Just who you wanna be
And every night you shine
Just like a superstar
That's how the life is played
A ten cent masquerade
You're dressed, you walk, you talk
You're who you think you are
Street life, you can run away from time
Street life, for a nickel or a dime
Street life, but you better not get old
Street life, or you're gonna feel the cold…”

Simple & obvious:

"Everything must change
Nothing stays the same
Everyone willl change
No one stays the same

The young become the old
Mysteries do unfold
For that's the way of time
Nothing and no one goes unchanged

There are not many things in life
You can be sure of...” :
