I think we need a little more information.
Vinícius de Moraes, the Brazillian artist who wrote the lyrics for "The Girl from Ipanema" (and many others), was something of a Wellsian genius, himself. He was named after a character in Henryk Sienkiewicz's Quo Vadis, and published his first book of poetry at age 20, before having a classical education, taking a law degree, and then beginning a long career in the Brazillian diplomatic corps. He met and became a friend of Orson Welles, when he welcomed him to Brazil in 1942 as part of his official duties. Moraes is said to have studied film with Welles and Greg Toland, when he was stationed in LA during 1947. He wrote the play on which BLACK ORPHEUS was based, a film Welles had an interest in.
But the reference to ORSON'S BAG doesn't ring a bell.
