There has to be a certain amount of love just in order for you to survive together. I think a lot of groups have gone down the tubes because they were not able to relate to one another.
The fact that there are singer-songwriters dealing with substantive issues is encouraging. It's important for young people to perceive that there are acceptable avenues of dissent, because we live in a world where dissent is hard-pressed; treated as if it were unpatriotic. I've always liked the concept of the loyal opposition. It allows for dissent to be a respectable part of the whole.
If you're serious about singing or acting, which are two art forms that get repetitive, the way to keep the music fresh is to recognize that it is totally impossible for it to ever be the same, night after night. You open your mouth and you'd like a certain sound to come out of it, but it doesn't always come out exactly like you thought it was going to come out!
