Karma, man
On this date in 1970 John Lennon performed 'Instant Karma!' on BBC TV's Top Of The Pops, becoming the first Beatle to have appeared on the show since 1966. Lennon wrote, recorded, and mixed his new single, all in one day. It ranks as one of the fastest-released songs in pop music history. Lennon later stated, "I wrote it for breakfast, recorded it for lunch, and we're putting it out for dinner."
Songs that talk about some sort of karma or FAFO-ness will work today.
