So did Jem say who did the drums for #4?
No - I got the impression that the drums would be split between a couple of people - both unnamed.
Sounds as though they have spent a lot of time narrowing down the field. They can all play drums but it will take someone special to fit in with the three of them and I don't think they are 100% sure yet, so no announcement at the moment.
In the Frostieverse*, patience is a requirement.
