I Know Why (And So Do You) (Patreon)

For the September's Bonus tabs we have Glenn Miller's song called I Know Why (And So Do You). The song was recorded in 1941 for the movie Sun Valley Serenade and Pat Friday sang the vocals. 

The song is in the key of C major and most of the time it involves a basic turnaround progression C - Am - Dm7 - G7. The form is standard AABA with an additional A part as an Intro. Hope you'll enjoy another time travel to the past ;)
