Thank you so much for posting the photos, My parents had that barrel table set. Probably got it from Penny's. It is exactly like theirs. They put it in their game room.
Several years ago, Mom updated the room and the table and chairs went to the yard sale. Just recently when my college age daughter moved into her first apartment, she wanted that table so badly, she thought it was sooo, cool.
Many a fun time was shared there playing games.
As to the matching western outfits, that is what one wore to go line dancing, aka Urban Cowboy.
