The live Carnegie Hall recording of February 21th 1963 of the “It’s A Raggy Waltz” appears on “The Dave Brubeck Quartet at Carnegie Hall” and on “The Best of the 50’s and 60’s” but are not the same lenght (7:14 vs 6:41).
You can listen to the long recording at https://www.youtube.com/watch?v=-jOiAN2BZEA. On the short recording there is a fade at the end and cut at 6:37.
The cut part from the long version is the presentation of the next song.
They have the same AcoustID (9d78f7ca-6a02-4e0a-9e3a-a35c7eb33908).
Are they two different recordings or can I merge them?
