Nobody had this on their bingo card, and that’s precisely what makes it so good. Paramore’s Hayley Williams joined Wilco’s Jeff Tweedy on The Late Show for a special collaboration covering Unknown Mortal Orchestra’s “Ffunny Ffrends”, performed in honour of the Late Show staff as the programme enters its final weeks. Williams played theremin alongside Tweedy’s half-moon guitar, and the combination worked with a natural ease that only happens when two genuinely gifted performers find an unexpected common frequency.
