Willie Nelson pays tribute to friend Frank Sinatra on new album

Over the course of his 60-plus year career, Willie Nelson has done a little bit of everything.

He’s got more than 150 studio albums, live albums, compilation albums, collaboration albums, soundtracks and Christmas albums to his name, has appeared in both movies and TV shows, has written multiple autobiographies and advocates for Farm Aid, marijuana legalization, the LGBT movement and better treatment for horses.

Even still, his next project, “My Way,” a tribute to Frank Sinatra, might seem a little out of left field.

On paper, Nelson and Frank Sinatra were like oil and water.

Nelson is a Texas-born outlaw country singer known for his trademark braids and bandana.

Sinatra, who passed away in 1998, was a New Jersey-born crooner who was also celebrated for his appearances on the big and small screens.

Nevertheless, the two were close friends and mutual fans.

Sinatra opened for Nelson in 1987 when the latter performed at the Golden Nugget casino in Las Vegas, and the two appeared in a public service announcement promoting the positive aspects of space research the same year.

In the PSA, Nelson calls Sinatra “Francis,” and Sinatra refers to Nelson as “this casually dressed gentleman.”

Nelson appeared on Sinatra’s “Duets II” in 1994, performing “A Foggy Day.”

“My Way” will be released in September and follows “Last Man Standing,” which was released in April.

“Though he was a million miles from western swing, he had a sweet swing of his own,” Nelson said about Sinatra in his 2015 autobiography, “It’s a Long Story.” “There was a tenderness to his voice, a purity and ease of phrasing.”
