1. Bob's explanation makes sense. Another Trio song credited to Samuel F. Omar is "Lei Pakalana" from Children of the Morning. I'm sure that was a Trio arrangement because they had been performing that song since the Purple Onion days (when Crosby was still a kid).
2. In the '60s, a San Francisco group called Blackburn & Snow recorded a song called "Stranger in a Strange Land" that is credited to Samuel F. Omar.
3. Crosby apparently admitted writing "Stranger in a Strange Land." An instrumental version appears on a Byrds re-issue and is credited to Crosby, not Omar.
4. Here's the weird part: Blackburn & Snow were managed and recorded by Frank Werber/Trident.
5. How could Crosby and the Trio have both independently choses this relatively unusual name as a pseudonym?
6. Since the only Samuel F. Omar song that we know to have been written by Crosby appears on an album produced and recorded by Werber, is it possible that this whole mystery is nothing more than a clerical error in the Trident/Werber offices?
Any other theories?
