After starting rehearsals for the tribute show for Brad, I noticed that my voice was cracking and would drop out in the middle of lines. This is something that I never experienced in any of my years as a vocalist. I decided to see a doctor who specializes in this field. After looking at my vocal cords with a scope, I was diagnosed with a ruptured blood vessel. It makes it very difficult to sing. The bad news is that I will not be able to perform at the tribute show for Brad. This breaks my heart because of the years I sang with Brad in Boston. He was one of my closest and dearest friends ever.
The only good news from all this is that this problem can be cured by laser surgery. I will fully recover my voice with this procedure.
I am very sorry to the fans who were expecting me to be performing at this great show. I was to sing with Orion The Hunter and to perform the last song of the night "Don't Look Back" with Boston and former members, Barry Goudreau, Sib Hashian and Fran Sheehan. I plan on being there to support all of the entertainers and to pay tribute to my friend Brad Delp.
