Merle Haggard

The Oscar winner would do his own singing.

On May 22, 1970, 'Okie From Muskogee' hit No. 1 on the charts.

On May 16, 1979, "the Hag" recorded "Workin' Man Blues", from his 'A Portrait of Merle Haggard' album.

Did you know he played on these hits?

There are a number of country stars who enjoy a bit of marijuana every so often, or have at least tried it -- including some who may surprise you.

What's your No. 1 pick?

These are lyrics that we'll be quoting forever ...

You know you're a legend when you get name-checked -- and Haggard's name comes up in quite a few country songs.

On March 14, 1970, Haggard scored his ninth No. 1 hit.

Rest in peace, Biff...
