Studio set back

I got an unexpected email today in respect of my studio time.... They cancelled one of the days!!!!! aaahhhhhh!!!! that means over the easter break I have one full studio day!!!! Luckily I planned ahead and I have left ample time to get what i need done. On the tuesday when i am in i have the keys and vocalist coming in, so in the morning i should be able to get the majority done. Im hoping to get things done by the 2nd week in April leaving the rest of the time for mixing and any other write ups....
