NBC's America's Got Talent revealed its fourth and final group of five Top 20 Round contestants during Tuesday night's live broadcast of the reality competition series.

Prior to performances of the first group of 10 acts that had previously been voted into the Top 20, Talent host Jerry Springer revealed that Nuttin But Stringz, Kaitlyn Mahar, Eli Mattson, and Donald Braswell had all been among the top four vote-getters after their performances last Wednesday.

During the process, Jerry also revealed that The Dallas Desperados Dancers, Indiggo, Flambeaux, and Dorae Saunders had been among the bottom four vote-getters and would be eliminated from the competition.

As with prior eliminations, judges Piers Morgan, Sharon Osbourne and David Hasselhoff were then left to decide which of the two acts with the fifth and sixth highest amount of votes -- former Chippendales dancer-turned-singer Bryan Cheatham and tap group The Tapping Dads -- would claim the final Top 20 spot in the competition.

"This is quite a tricky one for me" Piers dryly said of the choice, adding that it was a tough decision to choose either "the cruise ship crooner" or "Fred Astaire's worst nightmare." However, he ultimately chose the Dallas, TX singer.

Disagreeing with Piers, Sharon had no doubt in her choice.

"For me Without a shadow of doubt it has to be 'the Dads,'" she said, supporting the Temecula, CA tap dancing group.

"I hate this job," joked David after being left with what Jerry described as "the biggest decision" that "comes down to you alone" in deciding vote between the two acts for the final top 20 spot.

"Tapping Dads," he said amidst cheers form the crowd. "You're not the best dancer in the world. You're dancing for your daughter, great. You've got a great heart, I find you wildly entertaining and I think you could sustain in Las Vegas."

"Brian you have a major career ahead of you man. You've come a long, long way from Chippendales," he said among more cheers when referring to the Dallas, TX singer before adding that he felt Brian could potentially  headline in Las Vegas.

"Life's a learning experience. I know I've got a long ways to go, I think you've got a ways to go," he continued to Brian before turning back to the 'Dads.' "Tapping Dads. I think you guys have got a ways to go. But it's a competition. Who will be the best new act in America? My decision, the Tapping Dads!"

Following the eliminations, the first 10 acts of the Top 20 performed. They included:

- The Cadence, drummers from Springfield, MO
