"Gregg was one of the greatest Southern Rock/R&B singers of all time, having a unique blend of Country, Soul and Rock. In fact, he virtually invented the genre. I had been lucky enough to sing with him on a couple of occasions, and aside from being an incredible musician on both guitar and keys, he was a great person, and I feel very blessed to have known and worked with him. Music has lost one of its greats, and he will be remembered for his work for a very long time." - Steve Winwood
