The musical career of Genesis could use some tweaking to make sure their golden era would last a little longer.
I'll travel back to England in 1948 to get my doctor's education, which will get me the chance to "accidentally" remove Phil Collins' vocal chords when he's still young. After that, I will teach at Charterhouse and help Anthony Phillips to conquer his upcoming stage fright. Furthermore, I plan to teach little Anthony Banks a few harsh lessons in humility.
Next, I will intercept the demo they try to send to Jonathan King and will offer them a contract, if they agree to the inclusion of extra guitarist Steve Hackett and that weird mute drummer Phil Collins right away.
This contract must be signed in blood and it means no one can leave the band for all eternity.
