The group have decided to call off their 'Wonderland' live show in light of recent events in Manchester.
Barbra Streisand is to make a rare appearance on late night television next week.
The legendary singer is set to be a guest on Jimmy Fallon's Tonight Show on Monday (September 15), NBC confirmed.
She will promote her new duets album Partners on the show and it is Streisand's first guest appearance on a US late night talk show in over 50 years.
She was previously a guest on the Tonight Show in 1963, but made a brief cameo on David Letterman's Late Show in 1994.
