But I thought it could explain this bit of King Kunta by Kendrick Lamar
“When you got the yams—(What's the yams?)

I can dig rappin', but a rapper with a ghostwriter?
What the funk happened? (Oh no!)“
maybe he’s talking about the bass players Yam - Yammy - Yamaha????
but then realise thundercat plays Ibanez so possibly not
