"Deep" is a song by British boy band East 17. Written by Tony Mortimer, it was released on 18 January 1993 as the third single from the band's debut album, Walthamstow (1993). The song became their first top-five hit in the UK, charting at number five on the UK Singles Chart. Following the lackluster commercial performance of previous single "Gold", "Deep" returned the band to several international music charts, making it to the top 10 also in Australia, Ireland, Sweden and Zimbabwe. It is the band's only single to appear on the main Billboard chart in the United States, peaking at number 23 on the Bubbling Under Hot 100 in September 1993.
