Below is from the song you requested on Sister T's site...
If the chords read like below for slash chords it's RH/LH (ie., first chord = BbMaj over AbMaj or Ab as the Bass Note)
Bb/Ab - Oh
Gm7 - Oh
Ebm6/Gb - Oh
Bb/F - Oh
C7/E - see if
Eb/F - You are
Bb - real
On LGM written out it equals LH/RH as larrimo pointed out:
Bb/Ab = Ab/Bb-D-F (the Ab probably just meant the Bass note in this case and not a chord)
Gm7 = G/G-Bb-D-F
Ebm6/Gb = Gb/Gb-Bb-C-Eb
Bb/F = F-Bb-D/F
C7/E = E/E-G-Bb-C
Eb/F = F/Eb-G-Bb
Bb = Bb/D-F-Bb
