This is not the first time Journey and Def Leppard have gone on through the night on tour together. The hit-laden bands from either side of the pond hit the road together during 2006, at an interesting time for both. Journey was thrown for a loop when singer Steve Augeri, who had replaced Steve Perry eight years prior, had to bow out near the start of the tour due to throat problems; Jeff Scott Soto was hastily added to fulfill the dates.
