Overnight viewing figures show last night's Saturday Night Takeaway had 7 million viewers, a drop of 400,000 from last weekend's opener.
Despite the week-on-week decline, it was the most watched show of the night by some margin and had a peak audience of 8.5 million.
Over on BBC One, Let's Sing and Dance for Comic Relief launched on BBC One with an average audience of 3.4 million.
The show previously aired back in 2013 then as Let's Dance but has returned for this year's Red Nose Day with singing added to the mix.
The first of three live heats, which saw two celebrities voted into the final at the end of the month, was watched by a peak audience of 4.3 million.
Meanwhile, following Saturday Night Takeaway, The Voice UK's first live show kicked off with 5.1 million viewers.
The number is the lowest rating for a Saturday episode of the series so far - down 100,000 on last weekend - but up a good million viewers on last Sunday's show.
When on BBC One last year, the first round of knock outs - which weren't live - had 5.3 million viewers.
The Voice UK returns to ITV tonight for its latest Sunday episode of this year's show with the second of four live knockout round shows.
