There was a period of time (which I think has finally, mercifully, passed) in which people were having "Every Breath You Take" by the Police performed or played at their weddings, apparently without realizing that it's a song about stalking. In both that case and this one...
1. The title is something that fits the occasion
2. The melody is pretty
3. Nobody actually appears to understand the content of the song, which is in No Way appropriate for a wedding
So for people who DO understand what the song's about, seeing it trotted out at a wedding (and in this case, sugared up a good bit), it's a little off-putting. Don't want to sound like a grumpy old crank or a kill-joy, but this is really odd to behold for fans of Leonard. It's like someone reading a selection from The Cask Of Amontillado right after they say their vows.
