I think the Mosaic might have been my introduction to Tina. I only bought all the albums with him as a sideman when they were reissued on CD. I trusted Mosaic as I had several earlier boxes, starting with Monk.
What a hassle it was back then to order a set! I got their brochure, filled out the order form and sent it to them in a registered air mail letter, along with a check drawn on a US bank which I had to get from my local bank, all costly and time consuming. When the parcel finally arrived, it was like three months after my first wish to get the box. So much easier today with internet and online banking.
