How To Play Girlfriend - Pebbles 

Shows how to play various parts of Girlfriend by Pebbles. Drum is not complete but gives you general idea.
I think originally these synths were used:
Strings: D50 which came out just before this song. It seems 2 strings patches were used: arco or similar strings and Jete strings to do the accent on 3rd note (I just played 1 part here).
Bass: I used DX7 base + chorus but I could imagine it could have been analog synth as well
