Pretty much impossible as far as I can tell.
When I contacted Alfasound saying that I was ready to order my resing, Simon responded with “Leave this with me and we’ll check with the vocal arranger and get back to you.”
I don’t know how long it would take, I tried replying to the email but there was no response, and I don’t know if they began scheduling the resing session before I could pay Simon, or if I should’ve told him that I was ordering it for personal use.
If any of you JingleMadders out there know, please tell me.
