I occasionally hear this song on the radio and this morning, on the way to work, I finally caught the name of the band. When I got home I found it, downloaded it, ripped it to windows movie maker, and posted it. I went through all this trouble, so you'd better listen to it if you know what's good for you, sonically speaking.
My first was a hand held plastic silver Magnavox but as I recall it took four triple A's. As proof you can find anything using Google, I found a photo of this exact same radio I had as a kid.
The Iguanas are a band out of New Orleans and they've been described as sounding similar to Wilco with a Tex-Mex bent
