Using a Streets of London Midi file might drive you mad.

The link below shows the chords and the screenshots below from my PDF of Guitar Pro version shows the basic layout of chords in Verse and Chorus. In verse it is one chord per measure but in the chorus there are some walk-downs (2 chords per measure) at 144 BPM.

If you type them into BIAB and choose a good fingerpicking style you may get close to an exact match.

Or, you can ping me on PM and I can send you the pdf. But you should be able to figure it out from what I have provided.

Have fun.
