Nothing but a shithead who lucked out with a few hit tunes.
Mustang Sally is one the most overplayed songs for any classic rock cover band. It’s one that makes you say, “I can’t believe this band is going to pull out that crappy tune, again”.
I agree completely. So many of these R&B acts are treated as icons, but in reality make music that is virtually un-listeable or mediocre. Look at James Brown, for example. Or Sly Stone. Or even BB King.
