"Get It Up" is a song by The Time, from their 1981 debut album, and is their debut single. Like most of the album, the song was recorded in Prince's home studio in April 1981, and was produced, arranged, composed and performed by Prince with Morris Day later adding his lead vocals. Revolution keyboardist Doctor Fink provided synth solos on the track, uncredited.
The funk- pop number relies on synthesizers and contains numerous solos throughout the song. The song's propelled by a strong bass line and contains live drums and handclaps. A raunchy guitar solo provides a rock element to the funky track. "Get It Up" is basically an ode to sex and Day's attempts to get some. Prince's vocals are very apparent in the song, both in the background and the lead at times.
"Get It Up" was only released as a 7" single with the poppy "After Hi School" as its B-side. "After Hi School", while not an outstanding effort was composed by Dez Dickerson and is perhaps the strongest pop effort on the album. Along with the track "Cool", "Get It Up" peaked at number 6 on the Billboard Hot R&B singles chart, and at number sixteen on the Disco Top 80 chart. The full version of "Get It Up" was later a B-side for the 12" single of "Ice Cream Castles" in 1984. "Get It Up" is one of The Time's more popular numbers, and a live version of the song recorded at the House of Blues in 1998 was included on Morris Day's 2004 album, It's About Time where it segues into " 777-9311".
"Get It Up" is a song by American hard rock band Aerosmith. Written by lead singer Steven Tyler and guitarist Joe Perry, the song was released in 1978 as the third and final single from their album Draw the Line. The single also included "Milk Cow Blues" as a B-side. The single failed to break into the singles chart. The guitar is noted for its usage of slide guitar. The single had a reference to the next track on the album, "Bright Light Fright". The song was played occasionally by the band during the Aerosmith Express Tour from 1977-1978 in support of the Draw the Line album.
