I just emailed Levin about the date discrepancies and this was part of his response:
No wonder that "November" night was so "balmy." I wrote about Cecil at The Take 3 as I remembered the experience, without bothering to refresh my memory or to check my facts. Cecil played The Take 3 before and after he went to Scandinavia and I erroneously recalled both gigs as one. I thought my memory lapses were limited to the short-term variety. Thank you. I obviously have some editing to do.
