Exhaustively researched. Good stuff comes from the combination of Lighter's broad and long study of songs and literature with the resources offered by recent technology.

I'd venture to guess that the now-available information (or at least the comparative ease of access to it) makes the established knowledge of songs from even 10 years ago potentially obsolete. Lighter has built upon long standing familiarity with info found flung far and wide. Don't assume we "know" the "story" of any of these songs yet until reading things like this.

I can see Dick's series going on for a long time...there are lot's of songs out there!
