I have sheet music of this song arranged for quartet. The lyrics are very similar to those posted by Jim Dixon above. I have three brothers and we have sung this song at each others wedding receptions with our Dad filling in the fourth. We have substituted other names in to fit the intended audience and it is always hugely popular. I'd love to find a copy in better condition as mine is pretty beat up, but you can still read it and sing it. If anyone is interested in a copy I could email you a scan of what I have, I'll check to see it doesn't violate anyone's copyright.
