I wrote you a song

I got the rhythm right, wrote the whole darn thing in rhyme
Keeping out daylight keeping in time
Cruising along where crucial belongs
I wrote you a song

I put the effort in to effect
Encircling the circumspect
With the scale of my scansion
Put the man into mansion
I wrote you a song

My style alone no xylophone
Could temper the tempo
Alter the alto
Allow you to leave
Belie v believe
I wrote you a song
