This weekend The Grand Ole Opry is celebrating their 81st Birthday, and they have some great bluegrass on both the Friday and Saturday night shows.
Later tonight, Ricky Skaggs & Kentucky Thunder with special guest Earl Scruggs will perform twice on the WSM radio show. They’ll be on in the 8:30-9:00 and 10:30-11:00 p.m. slots (EDT). The Whites will be featured in those same segments.
On Saturday’s show, The Del McCoury band will be on in the 9:30-10:00 p.m. and 12:30-1:00 a.m. slots. Bobby Osborne & The Rocky Top X-Press will be on in the midnight to 12:30 slot.
You can hear the Opry program live over the air (650 AM out of Nashville) or via online streaming, between 8:00 p.m. and 12:30 a.m. (EDT) on Friday, and between 7:30 p.m. and 1:00 a.m. on Saturday evening.
WSM also maintains an audio archive which includes both the Friday and Saturday Opry broadcasts. It seems that they only archive part of each Opry show, but you can access what they have on the WSMonline site.
