The song Mom, It's Your Birthday was written by Candace in "Mom's Birthday". She wrote it early in the morning when Phineas and Ferb came to invite her to participate in their plans for their mom's birthday. The boys recorded the song without Candace knowing and play it back for the big video presentation that evening.
Lyrics
Mom it's your birthday
Thanks for all the care and love you give
Not to mention the meals
Sometimes I get kinda nervous
And forget to tell you how I feel
Im a little high strung
Its just because Im young
Mom I adore ya
And Ill do anything for ya
Although my brothers make me frantic
With every single crazy antic
And when I'm bouncing off the walls
You're the one who stays calm
Because you love me for who I am
I'll always love you mom.
