Expecting her first daughter, Alice Faye could not play the part of Vicky Lane.

In 1942, the time of this film's release, Betty Grable first achieved placement (at number eight that year) in Quigley's Annual Top Ten Money Makers Poll, where she remained annually through 1951 (when she netted third position). Miss Grable topped the list in 1943.

In Helen Forrest's 1982 autobiography, "I Had the Craziest Dream" (co-written with Bill Liddy), the vocalist with Harry James and His Orchestra recalled being baffled as to why costume designer Earl Luick would dress her in Native American garb for her walking-while-singing entrance midway through the smash ballad, "I Had the Craziest Dream" (music by Harry Warren, lyrics by Mack Gordon).

For the "Lux Radio Theater" version, Carmen Miranda delivered a samba which had not been featured in the movie: "Tico Tico" (music by Zequinha de Abreu, Portuguese lyrics by Aloysio de Oliveira). This fast-moving number soon would become a Miranda specialty. She would record it for Decca on January 27, 1945, and then in Copacabana (1947), Carmen would perform it as a song-and-dance routine.

"Lux Radio Theater" broadcast a 60-minute CBS Radio adaptation of the movie on May 22, 1944 with Betty Grable and Carmen Miranda reprising their film roles, plus Dick Powell stepping into John Payne's part. According to Grable biographer Tom McGee in his 1995 book, "The Girl With the Million Dollar Legs," Betty had been disappointed in not getting to sing on screen the classic wartime love song, "I Had the Craziest Dream" (music by Harry Warren, lyrics by Mack Gordon), the tune being assigned to the Harry James vocalist Helen Forrest. In the radio adaptation, Betty and Dick shared the ditty twice -- first a complete rendition and then a partial reprise at the end.

The Gordon-Warren song "Run Little Raindrop, Run" sung by Betty Grable and John Payne was written specifically for "The Great American Broadcast" and was to be sung by Alice Faye. The reasons why it was not used in "Broadcast" is not clear although the sheet music was published with the words, "Sung by Alice Faye."

Eight months after "Springtime in the Rockies" appeared in theaters, Harry James and Betty Grable wed (July 5, 1943). It was the second marriage for both of them. Grable had divorced first husband, Jackie Coogan, on Oct. 8, 1940. James's divorce from first wife, Louise Tobin, was finalized just two days prior to his marriage to Grable. They stayed married more than 22 years, divorcing on Oct. 9, 1965.

McTavish said he had been in college 20 years and earned diplomas from five colleges. In 1922, when he was a freshman at Harvard, his Aunt Stefanie died. Her will provided him with an allowance of $10,000 per year so long as he was in school. In 2017 dollars, that would be nearly $140,000. That would more than cover the annual tuition and room and board of America's most costly schools. In 2017, Harvard, Yale, Stanford, MIT, and Johns Hopkins costs all were in the mid-$60,000s. The tuition at Oxford and Cambridge for non-EU students in 2017 was $28,450.
