The MBTA became the "Yellow Line" Friday afternoon when waify Alaskan pop star Jewel boarded a car from Boston College to South Station for a free show to promote the Verizon Yellow Pages , which is working to make its product more hip in response to competition on the Internet.

Someone, please, fill in the missing part of the story.

For some reason, I won't be able to sleep tonight unless I know ... how did Jewel get from Boston College to South Station via the MBTA? Did she take the Green Line to Park Street, then switch to the Red Line to South Station?

Why was this left out of the article?
