trying to figure out rhythm chords for this schenker song

[len]

tune is called "searching" from 'the odd trio' album where he played all the instruments himself ... looked for tabs in all the usual spots but this is kind of obscure
just do not have an ear to pick this up and was hoping someone lend me one
much appreciated

Am, F5, G5, F5 is what I'm getting as the very first chords before everything else kicks in.

You can hear the C of the Am.
