The Velvet Underground. "I'm Sticking With You" originally appeared on the album"VU", but an alternative version, recently appearing in Hyundai car adverts, can be found on the "Fully Loaded" version of 'Loaded'.
I keep getting asked this at work, I know its velvet underground but this fella wanted to know the actual singer, who I`ve found out is Nico, unless someone corrects me on this.
