Glad to see the identity of the often-used ball song "Frat",used throughout as also is "Stand up"from Warner's own 1937 "Hollywood Hotel" is used in the open';Friz, who'd returned from MGM doing a few shorts like "Katzenjammer Kids", based on the long running strip,is billed as "Isadore" (his actually name) just as in the old days..
The gags, including the scalper gag (though as someone else's already said,not PC these days--with SOME people!) thru the closing gag with the "Charles Laughton" guy in the running "pardon me" (which Friz reused in one of his best, 1948's "Hare Do"). (From Jack Benny and Mary Livingstone's radio bit, one of many Benny references that first Warners and later Hanna-Barbera on Flinstones, and IIRC sometimes other studios, would use) are memorable, even if they're reused (as the above film movie reference mentions) from Friz's (first "Merrie Melodies" trademark theme-song cartoon, "Boulvevadier from the Bronx", which explains how a cousin of Porky with heavy Eugene Levy-like eyebrows batting from the 1936 short returned.) The 1969 retracing typically freezes Charles Laughton's temper at tend so he is just stand still with the sound effects.Good no one was there to catch him..what would a sequel to this cartoon be like..the cops arresting him for this!!!?? (They probably would TODAY if this cartoon were made..today the Laughton guy tearing the stadium apart reminds me of Lindsay Lohan or Ozzie Osbourne "tripping" as the "William Tell Overture"'s "The Storm" form Disney's first Technicolor Mickey,1935's "Band Concert", plays on soundtrack.) And I agree with the poster who said (ala Cyndi Lauper) the guys who did this just wanted to have fun..(I know not my own comment but it was a excellent description.) PS I noted that the credits for many releases from 1940 that Freleng directed seemed to have these credits at the bottom!
