well I think so when looking to your question, I can't stop thinking it implies that you think that a drummer can't play drums and sing at the same time or that it's something really good hower in a studio you can do it after eachother. Multitracking.... not sure if I understand your question right though
"I joined the Cult of Frank/Nobody wanted to join my Culf"
It wasn't recorded simultaneously, but I bet he could perform it simultaneously if they happen to do it at a show. There are lots of lead singer drummers.
i guess i have not seen many drummers be the lead vocals on a particular track. i'm sure its nothing special, though. and like you said, it was multi-tracked.
on a related note....i hate when lead singers do NOT play an instrument.
