This "Fireman" certain misfires. The script was originally intended to surface as an Abbott and Costello picture, but fortunately for A&C, the studio had second thoughts and decided to use the script as a vehicle for Spike Jones and his City Slickers instead, with Buddy Hackett in the Costello role and Hugh O'Brian as a Bud Abbott substitute. It didn't work! Only the musical numbers were successful. The best of them was a loony rendition of "In a Persian Market" which had the double advantage of being out of copyright and didn't cost Universal a cent. A couple of the other musical numbers could have been moderately successful with audiences too, but they are made less appetizing by long drawn-out "comedy" inserts – especially the "Poet and Peasant Overture". Spike and his boys labor enthusiastically with ad libs as well, but director Leslie Goodwins (who often boasted that he had over two hundred director credits – he did indeed!) manages to make most of their gags fall flat. According to studio publicity, Abbott and Costello can actually be seen in the film, but I've not spotted them myself. According to IMDb, they are present in a "long shot"!
