The polls have led to substantially different shows throughout MMJ's tours of Europe and, currently, North America, with the group digging into its catalog for gems such as 'War Begun', 'Phone Went West', 'Butch Cassidy' and 'Bermuda Highway' in addition to staples like 'Evil Urges', 'Outta My System', 'Circuital' and 'Wonderful (The Way I Feel)'.
