Waterfalls was the follow-up to the hit from what solo album?
Waterfalls (Paul McCartney song) "Waterfalls" is a Paul McCartney ballad from his first solo album after Wings, "McCartney II". The song has a stripped-down sound, with McCartney only playing a Fender Rhodes electric piano and a synthesizer and singing, and a short solo most likely played on an acoustic guitar. It was released as a single with "Check My Machine" as its B-Side and reached chart position #9 in the UK. In the US, however, it was his first single ever to miss the "Billboard" Hot 100 chart, only reaching number 106 despite being the follow-up to the number one hit "Coming Up". In 2013, "Rolling Stone" rated it the #25 all-time Paul McCartney post-Beatles song, describing how it contrasted with Wings' prior single.
Up (Olly Murs song) "Up" is a song by English singer Olly Murs, released on 1 December 2014 as the second single from his fourth studio album, "Never Been Better" (2014). It features American singer Demi Lovato and is also featured on the deluxe version of Lovato's fourth album, "Demi". It was written and produced by Daniel Davidsen, Peter Wallevik and Cutfather, with additional writing from Wayne Hector, and Maegan Cottone.
