I had a patron today looking for the song 'Morning' by Edward Grieg, on the CD Solitudes by Dan Gibson.
I searched for a good five minutes before I could track it down. It wasn't under 'Gibson, Dan' at all, like the other CDs in the Solitudes series. It was under a completely different name. Luckily, it had the Grieg song on it, so we were able to positively identify the CD based on the song.
