My iPod served up She’s Leaving Home, a song from Sgt. Pepper’s Lonely Hearts Club Band. This song has no drums, bass, or guitar. We’re going to get this song soon as DLC for Rock Band when they offer the whole album.
From a certain point of view, Sgt. Pepper was a reaction against exactly the kind of band your Rock Band band is. Two guitars, bass and drums were boring to The Boys and they went into the studio to do something different. There are going to be a lot of songs from that album that are fun to sing, but boring and/or impossible to play.
I don’t think there are many rock albums of any kind that are good for DLC. There are almost always dud songs involved that shouldn’t even be offered. But I guess the allure of “get the whole album” is working, and I’m sure the sales support the concept. Sigh.
