So I am taking my son, age 11, to the concert and meet & greet in Boston on the 9th of December. I am wondering if it is possible for him to bring his guitar and have Joe sign it. Concern #1: would Joe be ok with this? Concern #2: would the venue - house of blues - have an issue with him bringing it in? Concern #3: what do we do with it during the show? and/or is there time for me to run it back to the car after the meet and greet, but before the show starts, or do I have to mind it during the entire show? Any thoughts or responses would be appreciated.
