A few years after that issue was resolved, George and Tammy reunited musically once again to release the album “Together Again.” After the album’s accompanying 35-concert tour ended, the duo rarely spoke to each other for the rest of their lives.
Tammy passed away from a blood clot on April 6, 1998, at just 55 years old. George managed to overcome his alcohol addiction later in life, but ultimately passed away on April 26, 2013, from hypoxic respiratory failure.
