It appears they have over a month and a half off between shows where they could record.
After their 4/11 show in Las Vegas, they are off until 5/27 where they'll be in the UK.

I know, it's wishful thinking but they (including Stevie solo) have recorded in a shorter period. All you negative b*tches can just suck it......
