I want to know the answer to the following question:
On what tour did Kanye perform "Hey Mama" and his version of Journey's "Don't Stop Believing" in memory of his mother?
All the background I'm provided with is that "He dedicated a performance of "Hey Mama", as well as a cover of Journey's "Don't Stop Believin'", to his mother, and did so on all other dates of his Glow in the Dark tour.". Is that enough to answer the question?
Answer: yes
