Well, the last part of their letter...
"It is infinitely harder to make a group work than a solo act, and that was the attraction and excitement for us. We wanted to succeed when confronted with the ultimate challenge. We may not have been able to get everyone on the same page.

Until then…
Shan & Aubs"
