I have the music, but alas, I have no scanner. If you are really wanting the music, I can send you a copy via snail mail. Good ole' Mr. Welk is still playing on my local public tv station, you might check with yours.
Meanwhile, here's what I can do you in text, I hope it's not too torn apart in the transmitting of this email:
