I like walking by myself because then I can sing to myself. I'm sure the people along my bus-stop-to-work route think I'm mad. I don't care. I don't need to attract friends or lovers; I do need to let the music out of my soul....or, you know, keep myself mildly entertained (the old-fashioned way!).
Standards in my repertoire: "In Love With A View" by Mojave 3, "Five Foot Two" that 20s classic, "Idaho" by Josh Ritter, "Superstar" by the Carpenters (I know it was originally by someone else, but since my voice sounds exactly like Karen Carpenter's...oh wait.), "Something's Coming" from West Side Story, "I Wanna Dance With Somebody" by Whitney Houston (the one I struggle the most with hitting the notes for, but also the one I sing with the most enthusiasm).
