It’s not a real event unless you draw a raffle at the interval, and I think that’s were American entertainment has gone wrong. ★ 1 A question for the Britishes: Outside of Count Binface, is “99” still in common use? Because the last few times I’ve been to an ice cream van and asked for a 99 their response has been “What?” Anyway, this is why Binface has my support. ★ 2 Weekly Vibes 17/7/26 A higher proportion of down-tuned guitars than is typical. #WeeklyVibes https://open.spotify.com/playlist/5F8LZ9rITzUcwrCV7GIScf ★ 2
