Unforgettable is a studio album by Merle Haggard released in 2004 on his own label Hag Records. The album consists mainly of covers of classic pop and jazz songs, such as the title track, popularized by Nat King Cole.
The album shows a lesser-known side of Haggard, moving away from traditional country to explore American standards. It was recorded in 2004 and produced by Haggard himself.
Although not one of his best-selling works, Unforgettable received positive reviews for Haggard's vocal versatility and ability to perform outside the country genre. No singles charted on country lists.
