I saw this years ago on mtv, it's set in london, with the band in the street. i think one wears a suit, it shows the big ben. the song is pop I'd say... the band should be british. the chorus goes If you know that I am here, if you know it's not clear..... bha hba and I believe... not much hu. I'd like to know the band oh , and since I'm asking this..another song,with a girl singer, quite bohemien. the video shows her in a house two stories, dressed with a fluffy dress and singing about a boy. ok this is even less to guess. but I think the word bohemien was in the song too. I think her name starts with N
