TSOTD is the Bert Wills Band.
They are a Southern Rock band from Texas.I have every album/CD they released in the 40 plus years since they formed.
Bert has recorded and or appeared with every singer/band from Eric Clapton to ZZ Top.
To date I have only met one person on the east coast who ever heard of the band and that guy is in a NY based band,
The signature song for the Bert Wills Band is Pavonne Sunset which can be heard along with many others on YouTube.
