I don't think he's arrogant. He's a joker, and he's confident in himself and he's happy with his achievements, but I don't think arrogant is the right word.LoL have you seen Tom? Tom is very arrogent and that comes across in interviews.
In the interview on the DVD, if Tom was truly arrogant he wouldn't have been able to say that everybody in Libera was equal and that nobody judges anybody else on how many solos they do. I think he honestly knows that Libera wouldn't be the same without every other person. They all contribute.
