America's Got Talent: Week 4 Part 1

NBC's "America's Got Talent" aired on Tuesday with the start of its fourth week of auditions. After introducing judges Piers Morgan, Sharon Osbourne and David Hasselhoff, the audience was credited as the fourth and scariest judge.

The first contestant in the episode was 38-year-old Jeffrey Widom, government contractor. His unique singing style could not get past the judges' "humble eyes," as he called them.

Others who failed to impress include opera singer Dorothy Bishop, contortionist Chris Evans and David Glass, who sang Elvis Presley's "A Little Less Conversation."

Tallan Noble Latz, 9, hoped to impress the tough crowd by playing the electric guitar. When host Nick Cannon asked Latz what he would do with the $1 million prize, he said, "I'd have my mom quit work so I can spend more time with her."

Finally, the audience was impressed by a performance. Latz's strumming skills sent him through to the Las Vegas round.

Tony Ferrante, a 74-year-old retired barber, arrived on stage decked out in 1970s style clothing. His freestyle disco number had the audience members on their feet but Morgan believed Ferrante would not be able to win the prize. Regardless, the performance was a success.

Arthur Gulkarov, another contortionist, danced his way to the next round. "At last we've got some glamour on our show," Osbourne told him. Following him was Nathan Burton, who put on a fantastic magic act, and African High Flyers, whose dance performance went to new heights.

Kelli Glover, who auditioned for the first season of "American Idol," brought her singing skills to the "America's Got Talent" stage.

"I'm not sure [if you could win]. We see a lot of great singers," Morgan said, but gave her a "yes" vote anyway and put her through to the next round.

A funny and clever dance number performed by the Platt Brothers received a standing ovation from the audience and "yes" votes from the judges.

A singing group of post office workers called The Spiritual Harmonizers closed the show. Their 10 years worth of singing together paid off. The performance left a spiritual impact on the audience.

"You're like a young Stevie Wonder," Morgan said to the lead singer.

"I'm so glad that we've been able to give you a stage," Osbourne said.

"I'm so proud of you guys," Hasselhoff added.

With that, the harmonizers are on their way to the next round.

The second part of the fourth week continues on Wednesday at 9 p.m.
