Well, that wasn't my experience, Ray. I did the lyrics editing for the Rise Again Songbook, a collection of 1200 songs. When we requested lyrics from songwriters or took them from songwriter-owned Websites, most of the lyrics were of high quality, but some were full of obvious errors and far removed from what the songwriter was singing. And sometimes the spelling was atrocious. It was clear that some songwriters just sent us a fan's sloppy transcription, possibly a translation that the songwriter hadn't bothered to even look at before sending it. So my point is that even if you got the lyrics from the songwriter or the songwriter's Website, they may not be correct. It's always best to proofread and compare with various sources. If you publish a songbook with sloppy lyrics, the blame will fall on you, not on your sources.

That being said, there were some really awful mistakes that got past our proofreading. Once your mistakes get into print, you have to live with the shame of those mistakes forever.
