Help recreating bubbly synth sound

[io1970]

Hi!

Can somebody help me recreate the bubbly synth sound in Dick Hyman's Alfie?

There's a preset over here: https://www.gearslutz.com/board/electronic-music-instruments-electronic-music-production/413095-recreating-bubbly-synth-sound.html -- but it's far from perfect. Can anybody think of ways it can be improved?

Many thanks!
