Per Billboard, Astro was a part of "UB40" for more than three decades; he left the group in 2013 to join Ali Campbell and Mickey Virtue to form a musical act of the same name.

The Birmingham, England-founded British reggae group was formed in 1978 by founding members Robin Campbell, Ali Campbell, Brian Travers, Norman Hassan, Earle Falconer, and James Brown.

Virtue and Astro joined the following year. The band remained intact until 2008 following Ali's departure. His younger brother, Duncan Campbell, replaced him.

"UB40" also paid tribute on Twitter by writing, "We have heard tonight, the sad news that ex-member of UB40, Terence Wilson, better know as Astro, has passed away... Our sincere condolences to his family."

The band is known for their hit tracks which dominated the Billboard charts like "Red Red Wine," "Can't Help Falling in Love," "I Got You Babe," "The Way You Do the Things You Do," and more.

The outlet noted that all songs mentioned above were cover versions. They were originally sung by notable music legends like Neil Diamond, Sonny & Cher, Elvis Presley, "The Temptations," and Al Green.
