This Famous Studios Noveltoon is really swingin'.
In "Hep Cat Symphony", an enterprising feline forms a 1-cat band, but his rehearsal is ruined by a mouse orchestra's rehearsal. The mix of jazz and classical music provides a showcase for Famous-Paramount musical director Winston Sharples, who puts a capper on the festivities with a rousing rendition of Rossini's "William Tell Overture", otherwise known to laymen as the theme of The Lone Ranger. Like, dig it, man!
Nothing short of awesome.
