In 1978, after the group had broken up, Kale discovered that the group's name had never been trademarked. He registered the name, and quickly formed a new version of The Guess Who. Kale has played with the reconstituted Guess Who off and on ever since, usually without the involvement of Bachman or Cummings, although the Bachman/Cummings/Kale/Peterson line-up did get together for a series of concerts and a live album in 1983/84. Kale's health precluded his involvement with the The Guess Who's tours of 2000-2003, which also featured both Bachman and Cummings.
Currently, along with original drummer Garry Peterson, Kale remains co-owner of the Guess Who name and band. He continues touring and performing with Peterson and The Guess Who.
