Friends的主题歌：i will be there for you是谁唱的？

Whenever the sunshine comes through
　　Whenever my thoughts turn to you
　　Whatever you want me to do
　　I will be there
　　(From: http://cn.clyric.com )

　　Whether i crawl uphill
　　Try to not be through the mill
　　Just as long as i fit the bill
　　I will be there
　　(From: http://cn.clyric.com )

　　If it's on a lazy afternoon in summertime
　　And you're drinking champagne and wine
　　Anytime, i don't mind
　　Even if i've got the blues
　　And after i pay all my dues
　　You decide to go for a cruise
　　I will be there
　　(From: http://cn.clyric.com )

　　And if it's on a lazy afternoon in summertime
　　And you're drinking champaigne and wine
