So! To encapsulate:

• Joe's birthday: good
• Joe: 40
• Joe's onstage skills: admirable for having lain dormant for 20 years
• Joe's wife: gracious and fetching
• The 80's theme: not followed as stringently by all participants as may have been desired, but still fun
• Cafe Diem: a fine venue for such an event
• Cafe Diem's female employees: appreciated
• Cafe Diem's inability to spell "Illbillys" properly: understandable

Thanks for playing!
