My 2nd attempt at mashed potatos: How about Adam is giving us clues where he and Queen are having additional concerts:
D - Dr. May, R - Roger Taylor, E - European Music Awards, W - Worldwide
Red Light clue - red light district is in Amsterdam where the 2013 EMA's will be held.
Trees - Urban dictionary definition for marijuana (another clue for Amsterdam)
Ashleigh also says the word down..Netherlands - Neder means down.
Perhaps tearing out the page and and redoing the picture references doing the EMA's again.
Dancing with Ashleigh (their version of a waltz, with saloon music playing in background I believe is Waltzing Matilda which is a popular Australian folksong to this day..so Australia will have a concert.
That's as far as I got...don't know about the mountains..no mountains in Amsterdam. Perhaps Switzerland??
As you can see I couldn't sleep last night and when my first attempt at mashed potatos failed I thought I would revisit some of the clues...oh well at the very least it was fun!
