The OG Wiggles is the name of the original lineup of The Wiggles. They are the first incarnation of the group, forming in 1991 and lasting until 2006 when Greg retired and passed on his role to Sam for a few years. The group saw a brief reunion in 2012, when Greg briefly returned and decided to stick around to retire with Murray and Jeff at the end of the year. The three of them passed their roles to Emma, Lachy and Simon.
