Favorite bonus tracks?

I feel like XTC has so many fantastic bonus tracks that improve their albums! I’m getting into Mummer rn on Apple Music, and with just the main 10 songs, it’d be a solid B+ album for me. Many enjoyable songs (“great fire” is a masterpiece), but didn’t blow me away. But when you add the 6 bonus songs? It goes straight to A for me! Jump, Toys, and Desert Island in particular are just fantastic! And from Big Express I love Wash Away!
