You could take their suggestion and accompany it with tall, cool glasses of milk (and, if you're actually entertaining teens I highly recommend it). However, you may just want a libation that's a bit lovelier. In that case, how about a big bowl of Champagne Delight Punch?
We have the Anchor Hocking Party Starter Punch Recipe Book (I'm going with early 1970s for this one) to thank for this punch. That's a lot of hooch! Whatever you imbibe, put some records on the turntable (find your nearest record store and purchase some if you don't have any) and lift a glass to Record Store Day!
