I have said this before, and I will say it again. Glen Campbell. I have about 50 Christmas discs of all sorts, pop, classical, etc., and I enjoy them all, but his first Christmas disc is in every way perfection. It was out of print for years in the US, and cost over $100 for one made in the UK. It is now available on a label called ICON inexpensively, check Amazon. There's a picture of Glen's face on the front outdoors, and it's snowing. Every song is perfect, and brimming with authentic feeling. The production is very good, he's right there up close with you. This disc is a must have! I feel so strongly about it that 3 years ago I ripped a copy for everyone in my family and mailed one to each of the eight. Get it! I've been listening to it for well over 43 years, and it NEVER gets old.
2nd and 3rd place go to The Carpenters double disc...so great, and Randy Travis' Old Time Christmas...beautiful.
