DETROIT, Michigan (AP) -- Four Tops frontman Levi Stubbs has died at age 72, according to the medical examiner's office.

The Four Tops, with lead singer Levi Stubbs (second from left), dominated the charts in the mid-'60s.

Stubbs was the lead singer on the Motown group's hits, which included "Reach Out, I'll Be There," "I Can't Help Myself," "Bernadette," "Standing in the Shadows of Love" and "It's the Same Old Song."

The Four Tops were distinctive in pop music history for having the same lineup for more than 40 years, from the group's formation in 1954 until member Lawrence Payton died in 1997. The other members of the original group were Renaldo "Obie" Benson, who died in 2005, and Abdul "Duke" Fakir.

Fakir is now the original Tops' last surviving member.
