Though he never ran for office, politics surrounded John F. Kennedy Jr. for all of his life.

The eldest son of an assassinated president, Kennedy made what was then considered his debut into the world of politics at the 1988 Democratic National Convention, where he introduced his uncle Ted Kennedy, a longtime senator. (A decade later, Kennedy would die at 38 in a plane crash with his wife and sister-in-law.)

While his DNC speech was acclaimed — it was reportedly met with “a two-minute standing ovation” — newly released video from Kennedy’s prep sessions reveal the bumps before the polish.

In an exclusive preview from A&E’s Biography: JFK Jr. The Final Year, premiering Tuesday night, Kennedy’s friend Steven M. Gillon recalls how he obtained never-before-seen video of Kennedy, then 27, rehearsing his speech.

“It’s interesting to see how rough these practice sessions were and then how smooth he was when he actually delivered the speech,” Gillon says in the preview.

Earlier this month he released America’s Reluctant Prince, a nuanced biography of Kennedy which reveals the complicated life he led beneath the legacy of his family name.

“He said he was two people,” Gillon, who met John at Brown University in 1981, sparking an 18-year friendship, recently told PEOPLE.

“He said he played the role of John Fitzgerald Kennedy Jr., the son of the president,” Gillon said then. “But at his core, he was just John.”

In the Biography clip, the rehearsal video shows Kennedy as he memorizes and reviews his speech about his uncle.

“I think John had that instinct: He got up there in front of those people and he just turned it on,” Gillon says.

Long a charmer, at ease in the spotlight that shone on him since birth, Kennedy had grown more accepting as an adult of the idea that his true calling was politics — like his father and uncles before him.

In his last months, Gillon previously told PEOPLE, “John was becoming more comfortable with his political ambitions. He wanted to run for governor of New York and his ultimate goal was to return to the White House.”

Gillon described a moment when John was watching the 1989 presidential inauguration of George H. W. Bush on television with a close friend. “John said he wanted to go home again,” Gillon recalled, “and by home the meant the White House.”

Speaking in the Biography preview, journalist and former presidential speechwriter Hendrik Hertzberg describes the buzz from Kennedy’s DNC speech a year before the Bush inauguration comment.

“He hit it out of the park,” Hertzberg says. “The whole world at that moment thought, ‘Wow, he’s going places. He’s not just Jr.’ “
