ChordPro Conversion from PDF

Hi All, I have around 100 PDF files that I have converted (roughly) to text files.
The first job would be to tidy them up and remove obvious conversion errors.

Second job would be to insert the primary ChordPro commands to convert from text to chordpro.

Somone used to working with a multi file text editor (eg EditPad) and familiar with RegEx would probably find the chordpro conversion easy as all files could be done at once.

EG:
DON’T LOOK BACK IN ANGER [C]
Oasis
Key C 82bpm Starting note [E]
Intro [C] [F] [C] [F]
[C] Slip inside the [G] eye of your [Am] mind,

Needs to become:
{title:Don't Look Back In Anger}
{subtitle:Oasis}
