Not pregnancy related but if you could see any singer or band in the world at no cost which would you see?

I'd see Aerosmith because i have like the hugest crush on Steven Tyler! He is so freaking amazing!

I'm going to see journey next month so it was a tie between the two but i am seeing journey for free (thank you mother and father in law)

Update: Steven Tyler is going on tour in July and I found 2 tickets for 265$.

But the concert is in the state over (I live in Oklahoma and its In Texas. )
