"I Thank You" is a song written by David Porter and Isaac Hayes originally recorded by Sam and Dave, released in early 1968. The single was Sam and Dave's final release on Stax Records, reaching #9 on the Billboard Pop Singles chart and #4 on the R&B chart. Shortly after its release, Stax severed its distribution deal with Atlantic Records and Sam and Dave, who were actually signed to Atlantic and loaned out to Stax, began recording for Atlantic proper.
ZZ Top covered the song on their 1979 album Degüello. The band released the song as a single the next year.
