Contribution declined - #260126-063650-748000

I recently submitted a trivia contribution for the film Squad Car (1960).  There was a nightclub scene in which one of the film's stars performed a song.  The club owner introduced the band, not listed in the film's credits but it was a name I recognized, so I submitted a trivia item giving a bit of the band's history, as follows:

"The nightclub band backing up Cameo Kincaid is introduced as The d'Varga Trio. Pianist John F. Anderson, who was usually billed only as d'Varga (but occasionally as John or Johnny d'Varga), became popular in mid-1940s Los Angeles as a solo lounge act as well as a bandleader. By the late 1950s he was heading a trio that played often in Palm Springs and other Southern California locales. In the 1970s he returned to his native Texas, where he continued to perform until his death in 1977."

After several days in "Pending" status, my contribution was declined because it "Does not meet contribution guidelines."  A review of the submission guidelines leaves me scratching my head; is it possible this isn't considered "interesting"?  And just to be clear, "Cameo Kincaid" is - for better or worse - the actual name of Vici Raaf's character in the film.

Can anyone help me make sense of this?
