With coauthor Buddy DeSylva on ukelele in musical Bombo. New version by Jolson in film Rose Of Washington Square ('39), in '46 in The Jolson Story and in '49 in Jolson Sings Again. Bombo's the musical also introducing Toot Toot Tootsy and April Showers. California Here I Come was a last-minute addition when he started touring with Bombo.
Al Jolson got credits just for being so kind to cut the song. Like Elvis one generation later, Al wasn't particularly notorious for his songwriting. Still he shares coauthorship on some of the biggest Tin Pan Alley tunes ever.
