A few days before his unexpected death, Tito Jackson attended a memorial service for his late brother Michael Jackson.

Tito shared a photo on Instagram last Wednesday of himself and his brothers Jackie and Marlon Jackson paying their respects to Michael, who died in 2009 at the age of 50, at the “beautiful” Orlando di Lasso statue in Munich before their concert at Circus Krone.

“We are immensely grateful for this special place that not only honors his memory, but our shared legacy. Thank you for keeping his spirit alive,” Tito wrote of the “beloved” King of Pop, who brought his “HIStory” world tour to the German city in 1997.

The Jacksons’ performance in Munich was ultimately Tito’s last performance: he died on Sunday at the age of 70.

The late guitarist’s sons Taj, Taryll and TJ Jackson, announced the news in a post on their band 3T’s Instagram account.

“We are shocked, saddened and heartbroken,” the brothers wrote, calling Tito “an incredible man who cared about everyone and their well-being.”

“Please remember to do what our dad always preached and that is ‘Love one another,’” Taj, 51, Taryll, 49, and TJ, 46, told their followers, using the title of Tito’s 2021 solo track. “We love you Pops.”

While the official cause of death has not yet been released, Steve Manning, a longtime Jackson family friend and former manager, told “Entertainment Tonight” that Tito suffered a heart attack while driving from New Mexico to Oklahoma.

Tito, born Toriano Adaryll Jackson, was best known as a founding member of the Jackson 5, which also included his brothers Michael, Jackie, Jermaine and Marlon Jackson.

The group’s hits from the 1960s and 1970s included “ABC”, “I Want You Back”, “I’ll Be There” and “The Love You Save”.

In 1997 they were inducted into the Rock & Roll Hall of Fame.

Since Michael’s death, Tito, Jackie, 73, and Marlon, 67, have continued to perform together as the Jacksons. It is unclear whether they will cancel their upcoming tour dates in the wake of Tito’s death.
