Despite their success, founding member Anthony Field almost left the group in 2004, shortly after his marriage and the birth of his first child, due to his serious medical issues, which were worsened by the Wiggles' demanding tour schedule. After meeting chiropractor James Stoxen in Chicago, Field improved his health to the point that he was able to continue. He began to hire teams of chiropractors for himself, his fellow bandmembers, and cast members in every city they performed, which he credited with making it possible for them to fulfill their touring requirements.
