Apparently Yes cancelled their entire tour because of this. "Yestival" with a 1 song from each album gimmick and they were touring with Todd Rundgren and Carl Palmer. So that's a pretty huge trek to suddenly cancel. Howe's other son is playing drums with Yes now too so this is a pretty significant tragedy for them. I haven't seen it announced what the reason for Virgil's death was, just that it was sudden and unexpected, so that's potentially some really intense shit they're dealing with.
