This one has those rock changes you hear everywhere, I-V-vi-IV, with a discordant transitional chord thrown in from V to vi. It's optional if you find it too much trouble. C/C# might not be the right name for it , but it works well enough--that said, let me know in comments if you have a better idea. To play C/C#, you can slide your index finger up to fourth fret , or slide your ring finger up to 4th fret . C/C# : x4555x C/C# : x42010 preacher's son tonight thought I wasn't with it, oh yeah (guitaretab.com)
