The past few weeks on The Voice Season 4 have been a real trip down memory lane for seasoned fans. On June 4, Season 3 winner Cassadee Pope returned to the stage to debut her new single, “Wasting All These Tears.”

The song hit No. 3 on the main iTunes chart and No. 1 on the iTunes country chart. She also performed it at this year’s CMT Awards.

But Cassadee isn’t the only Voice artist to return home with some new tunes. On June 11, Season 2’s Tony Lucca, and Season 3’s Terry McDermott and Nicholas David all performed their own singles on The Voice stage.

Tony sang his upbeat love song, “Never Gonna Let You Go.” The single is the first from his upcoming album, which will be released from his former coach Adam Levine’s record label, 222 Records.

Soul singer Nicholas David debuted his first single, “Say Goodbye” on the show, and it was full of his laidback flair. Sadly his coach Cee Lo Green wasn’t there to see it, but we know he would have been proud.

And Team Blake’s Season 3 runner up, Terry McDermott, performed his single “Pictures,” which made it to No. 1 on the iTunes rock charts earlier this year.
