Why are Reine and Linda Press not touring with Neil diamond?

Reine and Linda Press are not touring with Neil Diamond primarily due to personal decisions and changes in his touring lineup. Neil Diamond announced his retirement from touring in January 2018, following a diagnosis of Parkinson's disease, which significantly impacted his ability to perform live. Consequently, many of his long-time collaborators, including the Press sisters, have shifted their focus to other projects or personal endeavors.
