Recently I was at a Bluegrass festival in Tennessee. I was watching and listening to the groups rehearse before they went on stage.There where a number of groups preforming and all seemed to have a good warm up session, all where have a good time with no mistakes that I could hear. Then on stage things changed, a few of the lead singers forgot the words, but instead of blowing the song, another member of the group took another break to fill in the gap. It was real cool to see how, with a lot of practicing playing together you can overcome this mistakes and it was a relief to see even tight groups also have there moments:ohmy:
