Def Leppard guitarist Phil Collen had to miss a few of the band's early tour dates on their co-headlining tour with Journey. But he had a good reason - the birth of his son Jackson. Collen says his wife Helen nearly died from complications during childbirth, so he left the road to be with her in California. Trixter guitarist Steve Brown ended up filling in for three shows back in May. But everything worked out - Brown did a great job filling in, and Collen has a beautiful baby son.
