St Patricks Day books for kids. . .

What is it with St. Patrick's Day books?! I've got a St. Pat's storytime at a Headstart on Friday. I've put all the books we own on hold and 99.5 % of those books are WAY too long. Keeping the attention of 40 3-5 yr olds with these books is nearly impossible. Heck I think some of these books are way too long to keep Elementary kids attention. Looks like I'll be making up a felt story and singing. I'm such a bad singer. . .
