I want to know the answer to the following question:
What car manufacturer hired Petra Haden to perform a capella songs in commercials for their car?
All the background I'm provided with is that "In 2009, Toyota commissioned Haden to perform three songs for television commercials for the third-generation Toyota Prius, including an a cappella version of The Bellamy Brothers' 1970s song "Let Your Love Flow".[citation needed]". Is that enough to answer the question?
