7 down is skolio so 17 across must be pop! 31 across I think is cobb but cannot confirm that. Someone has already posted the answer to 37 down as tadlik.
Some confusion over 7d and 17 across, I see. I agree with Sarumite and Callboy.
7d is DEFINATELY Skolia. This is the plural (skolio must be the singular). As the question states 'drinking songS, Skolia is correct.
DAD is a dialect for thump (from Shetland, I think.) Since when have you thumped a balloon to burst it?? (for those of you who think pop is the correct answer!)
