Man, that harmonica is fast, like nothing less than 1/32nd notes. Love the organ take. Cool guitar, too. The soloists have such a nice bed to lay down their tracks. As Beth mentioned, it seems a little low in volume. YT won't raise the volume if it's lower than normal, but they will lower it when it is too high.

Thanks, Marty. Re the volume I'll quote my reaply to Beth:
Thanks, Beth. I'm surprised that you mentioned the volume because each time I do a channel-swap and remix I increase the volume of every stem file by 1db, so everything I'm now posting is louder than the original posts and no-one ever mentioned volume before. Also, there are a lot of lower volume recordings in YT and other sites, plus also on CDs. That said, there appears to be a trend towards making recordings super-loud, which I'm not pro. Here's a note from a PDF on common mistakes made in recordings from a guy who runs a local studio, which is alas just too far away for me to use.
Guidelines for a successful Studio Session (common mistakes to avoid)
MISTAKE 1: MIXING TOO LOUDLY
Mixing too loudly will actually just ruin your mix….
It feels great when you get a great sounding track and you crank up the volume. It can sound big and exciting. A lot of things sound exciting when you blast them but there are good reasons to mix at lower volumes. Working at a lower volume will ensure that your mix doesn’t sound too mid-range and enables you to hear the finer details in your mix and adjust them accordingly. Plus, one of the most important reasons is to protect your ears and those of others!! Exposure to any sounds at high volume are detrimental to your hearing and once you lose it, it never comes back
