Based on information in the Sessions History section of the Alphabet Town website, it appears that the only Harum Scarum cassette, Trick of Paris Season, was recorded sometime in 1989. Much more info from the liner notes are below but they don't state anything more specific about the dates of recording. The cassette    was self-released. The band was Elliott Smith, Garrick Duckler, Jason Hornick, and Tony Lash.

- The entire cassette was put on YouTube in 2022.

- This Bed is an early version of Blue Mood, a solo song Elliott performed live one time. 

- Catholic is an early version of Everybody Cares, Everybody Understands.

Cassette liner notes state the follwing info:

       Garrick Duckler - himself
       Jason Hornick - bass
       Tony Lash - drums
       Elliott Smith - guitar vocals

-  Produced by Harum Scarum. Engineered by Tony Lash and  Neil Karas (I think, hard to read).  Mixed by Tony Lash.

- Recorded at Palace Recording Studio and Sound Impressions.

- All songs written by Garrick Duckler and Elliott Smith except Small Talk by Garrick Duckler, Jason Hornick, Tony Lash, and Elliott Smith.

- Catholic arranged by Tony Lash.
