Neil Tennant and Chris Lowe make up the British electro-pop duo whose list of hits include "West End Girls", "It's a Sin" and "Always on my Mind".

The pair are one of the most successful pop groups in history and they have had a startling 42 top 30 singles in the UK alone.

They're musical style is a unique mix of electronic rhythms, synthetic beats and vocals and keyboard.

They've been called by some artists as one of the most influential musical acts of the 20th century and have helped to define a generation of electronic music.

The duo have also become somewhat of an icon in the gay world - Neil Tennant came out of the closet during a magazine interview in 1994 and Chris Lowe has not publicly said whether he is straight or gay.

In March 2009, the pair released their album "Yes" to rave reviews and just this month they released a live CD and DVD collection from a concert in London in late 2009.

Here's your chance to ask these iconic musicians your questions.

What was it like using electronic influences at such an early stage? Do you have any favorite artists you like to work with? What's your favorite song? What's it like being somewhat of a gay icon?

American Patti Smith is often referred to as the "Godmother of Punk" - an influential figure in the rise of the punk rock movement during the 1970s in the U.S.

Some of her most memorable albums include her 1975 debut album "Horses" and her hit song "Because the Night", which was co-written by rocker Bruce Springsteen.

Although Smith is well regarded in the music industry, the 63-year-old is also well known for her political activism on a variety of issues.

She was an open supporter of the Green Party in the U.S. and threw her weight behind the 2000 presidential candidate, Ralph Nader.

Smith also helped organize some of the first series of protests against the U.S. led invasion of Iraq.

In 2007, Smith was inducted into the Rock and Roll Hall of Fame and rock stars including Michael Stipe of R.E.M and KT Tunstall have all openly said Smith was a source of inspiration.

Today, Smith has a new book out called "Just Kids" which chronicles her life in New York City during the 1970s and her relationship with Robert Mapplethorpe.

And the Documentary “Patti Smith: Dream of Life” by Steven Sebring, had its national broadcast premiere on the POV (Point of View) www.pbs.org/pov/pattismith series on PBS last December.
