I must admit I find most of Hank Williams Junior's hard rock/country recordings to be loud and obnoxious. But there's one song he does that I never get tired of hearing -- Fats Waller's Ain't Misbehavin'.
It's certainly atypical of the majority of his recordings -- a very laid-back, gently swinging track that appeared on his 1985 Warner. Bros. album Five-O and was released as a single. Both the single and the album topped the country charts. The MP3 below is taken from the vinyl album.
Five-O has been issued on CD at least twice, the latest just last year, and is widely available. Strangely the complete album isn't available as a download, although Ain't Misbehavin' is. It's included in a 45-song digital compilation called The Complete Hank Williams, Jr., which is also available on CD. My advice is to stick with downloading only Ain't Misbehavin' unless you're a Bocephus fanatic.
This version of Ain't Misbehavin' from YouTube appears to feature Hank lip-synching the vocal, according to many of the posted comments. But this undated concert version is about a minute shorter than the recording, so I'm guessing the instrumentation is live. In any case, I'll let you be the judge.
