Singer Tony Orlando is reuniting with singers Telma Hopkins and Joyce Vincent -- collectively known as Tony Orlando and Dawn -- for back-to-back performances in Bethlehem.

The trio is scheduled for 8 p.m. Aug. 10 and 11 at the Sands Bethlehem Event Center. Tickets cost $35-$55. VIP tickets are also available.

Tony Orlando landed hits in the 1970s with the songs "Tie a Yellow Ribbon Around the Ole Oak Tree," "Candida," "Knock Three Times" and "He Don't Love You (Like I Love You)." Orlando, Hopkins and Vincent also starred in their own television variety show, Tony Orlando and Dawn. The group disbanded in 1977 and reunited in 1988 -- a reunion that was initially supposed to last five weeks but continued through 1993.

In addition to her music career (she can be heard shouting "Shut your mouth!" on Isaac Hayes' hit "Theme from Shaft"), Hopkins co-starred as Rachel Baines-Crawford in the hit early 1990s sitcom Family Matters. Her other acting credits include the shows Bosom Buddies, Gimmie a Break! with Nell Carter and Half & Half.

Orlando will return to Sands in November for a five-night residency of his "Tony Orlando's Great American Christmas" show. Dates are Nov. 27-30 and Dec. 1.

Sands officials also announced Monday that R&B group New Edition will perform 7 p.m. July 14. Tickets cost $69.50-$99.50.

New Edition's hits include "Candy Girl," "Cool It Now" and "Mr. Telephone Man." In 2012, the group -- which features singer Bobby Brown, who is the former husband of late R&B icon Whitney Houston -- New Edition was awarded the Lifetime Achievement Award during the Soul Train awards ceremony.

Tickets for both shows go on sale 10 a.m. Friday, May 27, through ticketmaster.com, sandseventcenter.com, by phone at 800-745-3000 and at the box office, 77 Sands Blvd.
