Good days, bad days
Living with all the highs and lows
With every step we take
Gonna remember the great days

Great days, every moment was worth it
Through the pain and through the pleasure
Every single memory was for real
Great days, gonna cherish it forever

Ones and Threes, Sixes and Nines
Gonna ride till the wheels fall off
With every obstacle we overcome
Gonna remember the great days

Great days, every moment was worth it
Through the pain and through the pleasure
Every single memory was for real
Great days, gonna cherish it forever

Every day is a journey of its own
Some days we're up, some days we're down
But when the sun sets, we gonna rise again
Gonna remember the great days

Great days, every moment was worth it
Through the pain and through the pleasure
Every single memory was for real
Great days, gonna cherish it forever
