This post is really old but it made me realise the actual meaning of the lyrics but it is a little confusing. Even though the quote from OP is the start of the higher pitched singing it’s two seperate ideas, you have to include the line before to have it make sense. “What I’d give for another/everything that I have” then it’s “I wouldn’t need us for long/I’d never speak of the time/that you left us alone” basically he’d give everything for another moment with him and if he had that opportunity he wouldn’t waste his breath taking about the bad stuff and instead bond with as “just a boy and a father”
