Caravanserai (album): Caravanserai is the fourth studio album by Santana, released on October 11, 1972.  It marked a major turning point in Carlos Santana's career as it was a sharp departure from his critically acclaimed first three albums.  Original bass guitarist David Brown left the group in 1971 and was replaced by Doug Rauch and Tom Rutley, while original percussionist Michael Carabello left and was replaced by Armando Peraza.  Keyboardist/vocalist Gregg Rolie, who was having a falling-out with Santana, was replaced by Tom Coster on a few songs.  "Caravanserai" reached number eight in the "Billboard" 200 chart and number six in the R&B Albums chart in 1972.

I Wanna Go Back: "I Wanna Go Back" is a 1984 song by American rock band Billy Satellite, written by band members Monty Byrom, Danny Chauncey, and Ira Walker, that achieved major popularity when recorded by Eddie Money in 1986.

Welcome (Santana album): Welcome is the fifth studio album by Santana, released in 1973.  It followed the jazz-fusion formula that the preceding "Caravanserai" had inaugurated, but with an expanded and different lineup this time.  Gregg Rolie had left the band along with Neal Schon to form Journey, and they were replaced by Tom Coster, Richard Kermode and Leon Thomas, along with guest John McLaughlin, who had collaborated with Carlos Santana on "Love Devotion Surrender".  "Welcome" also featured John Coltrane's widow, Alice, as a pianist on the album's opening track, "Going Home" and Flora Purim (the wife of Airto Moreira) on vocals.  This album was far more experimental than the first four albums, and "Welcome" did not produce any hit singles.
