Bad Case of Love ala Tommy Castro Blues in Bb The only thing non-standard about this song is that there are short verses and long verses. A short verse is the standard 12 bar progression. A long verse is I | % | % | % | % | % | I (with tacit) | No Chord | IV | IV | I | I | V | IV | I | I | Verse 2 and 3 are long, everything else is short.
