"[2] The magazine's Alan Jones wrote, "Michelle Gayle is easily the most accomplished singer to emerge from television drama in recent years — no apologies to Robson & Jerome, or any of their ilk — and her career as a recording artist should be furthered by her latest single, "Do You Know".

A jangly, semi-acoustic mid-tempo pop song, it allows Gayle plenty of room to demonstrate her fine vocal style.

Busier and more rhythmically accentuated house mixes deliver this one to the dance floor too, making its success all the more likely.

"[3] David Sinclair from The Times declared it as "[a] gently appealing, acoustic pop song more in the Joan Armatrading vein than the sugary sound of Gayle's previous hits.

In 2004, Dutch DJs Zentveld & Oomen, under the alias Angel City, created a track called "Do You Know (I Go Crazy)", which samples the lyrics of "Do You Know" and places them over the instrumental composition "Children" by Italian record producer Robert Miles.
