Yep, this was a great band -- one of the original blues/r&b showbands conceptualized in the 70's as part of the SNL features.
The first version of this band had really crack players in it -- almost a who's who of the Stax/Volt studio cats from the late 50's-60's -- among them:
• Steve Cropper - seminal rhythm gutarist from Booker T. & the MG's, Telecaster monster
• Donald "Duck" Dunn - seminal bass player from Booker T. & the MG's, P. Bass monster
• Steve Jordan - Drums, currently Clapton's drummer on his "bluesey" world tour
• Matt "Guitar" Murphy - tasty blues guitar player
• A bunch of guys from the Memphis Horns
They put an outstanding "tribute" album out as a first release called "Briefcase Full Of Blues". The big top 40 hit off that album was a re-do of "Soul Man". Pick it up if you can. Much better than the movies and all the other succeeding material combined. We cover a bunch of those tunes in the band I play in.
