and for those who haven't heard the stereo version of "I should have known better" with the harmonica stop fixed, as found on only the USA vinyl pressing of "reel music", then here it is on youtube ... it starts about 2.38 minutes in https://www.youtube.com/watch?v=yBzyBFx5JP0
The USA true stereo mix found on capitol pressings in the 1970's https://www.youtube.com/watch?v=vIXf14RYOhg the difference between that and the uk stereo being around 1.36 on this clip with the delay in backwards guitar being an extra 2 notes after John sings sleepy feeling
with "I call your name" somebody went to throuble of comparing the uk mono, the uk stereo and usa stereo with dave dexter echo (which was on the usa lp & the capitol cd box set vol 1)
The primary difference between the American and British mono mixes of "I Call Your Name" is still the cowbell, but they come in at the same time , the UK version has a more up-front of it...the USA mono has the cowbell more buried in the mix found here https://www.youtube.com/watch?v=OMY97KLBiXQ
