Mad Men, "Waterloo"

An old friend is gone
But Sterling Cooper lives on
Roger finds a way

Mad Men, "The Strategy"

No point in regrets
Wondering what you did wrong
So do it your way

Mad Men, "The Runaways"

They may want him out
But Don won't give up easy
Not without a fight

Mad Men, "The Monolith"

Don't you get it, Don?
If you want a second chance
You have to earn it
