I had this single when I was a teenager!
I thought that the flip side (Paintings on the wall) was brilliant.
It sounds like you are on the right path!
Great video, very interesting, Thanks
(It would also be interesting to compare a frequency sweep from 20 Hz - 20 kHz,. and then to analyze the waveform as a FFT display as well as a listening test.)
I have the sheet music for 'a little romance' and 'Rebecca' for sale on ebay.
Great songs by a great band that have stood the test of time.
