Best of Dark Horse 1976–1989 is a compilation album by the English musician George Harrison, released in October 1989. His second compilation, after the Capitol/EMI collection The Best of George Harrison (1976), it contains songs from Harrison's releases on his Dark Horse record label between 1976 and 1987. The album also includes a 1989 single, "Cheer Down", which was Harrison's contribution to the soundtrack of the film Lethal Weapon 2, and two tracks recorded specifically for the collection: "Poor Little Girl" and "Cockamamie Business". Despite the popularity of Harrison's work over this period – both as a solo artist with his Cloud Nine album (1987), and as a member of the Traveling Wilburys – the compilation failed to achieve commercial success.

"Cheer Down" is a song by English musician George Harrison that was first released in 1989. The track was his contribution to the soundtrack of the film Lethal Weapon 2 and was also issued as a single. Harrison wrote the song with Tom Petty and co-produced the recording with Jeff Lynne.
