As Teresa and Maeve and Pietro set out on a road tour, vaudeville theater owners were trying to fill theaters across the country with good acts to meet demand. They needed talented people.
How many acts were needed to fill US vaudeville theaters? There were approximately 8 to 15 acts, each 6 to 15 minutes long, in each theater per day. Some theaters had “continuous” shows from mid-morning to 2:00 am! Every small town had some type of theater and larger towns might have three or four. When Teresa walked out on the stage in 1913, there were more than 2,000 acts needed each day around the USA.
There are several good articles online that talk about the various theater owners, booking agencies, and labor unions. Fervent competition, underhanded blacklisting, and an ongoing struggle to control the market defined the experiences Teresa would have had as a singer. From the Theatrical Syndicate of 1896 to the Orpheum Circuit to the Pantages Circuit and the Western Vaudeville Managers Association, big money was involved and pressure was heavy on individual theater managers and performers. So much so that eventually unions were formed to protect the performers.
