Lou Reed's death leaves multi-instrumentalist John Cale and drummer Moe Tucker as the only living original members of art rock icons Velvet Underground. Cale, who co-founded the group with Reed in 1965, reacted to the news with a simple sentence on his Facebook page on Sunday.

"The world has lost a fine songwriter and poet… I've lost my 'school-yard buddy'" he writes.

Along with guitarist Sterling Morrison, who died in 1995, Reed, Cale and Tucker released two albums as a unit, 1967's "The Velvet Underground & Nico" and 1968's "White Light/White Heat," before Cale was replaced by Doug Yule later that year.

Nico, who contributed vocals to four songs of the band's debut, died in 1988.

Since leaving VU, Cale has released dozens of albums, including 1990's "Songs for Drella," a joint project with Reed in tribute of their mentor, Andy Warhol, who died in 1987.

Reed passed away on Sunday at the age of 71. An official cause of death has not been announced, however the singer-songwriter had undergone a liver transplant in June.
