What are the two songs bard paisley and Urban are trying to play in the beginning of the video start a band?

Led Zeppelin's "Stairway to Heaven" is the first one and I don't believe the other one is any particular song. However, during the second verse which Urban sings, Paisley does play a part to the guitar licks for "Layla" by Derek and the Dominos as well as "Sweet Child O' Mine" by Guns N' Roses.
