This song is a tribute to the American jazz pianist and vocalist Mose Allison. Allison was a major influence on a number of 1960s R&B bands including The Rolling Stones and The Who. The latter regularly featured a version of Allison's song "Young Man Blues" in their concerts.
Geffen Records made history on June 27, 1994 when Aerosmith's "Head First" became the first major label song made available for exclusive digital download. Download speeds at the time were so slow it took around 75 minutes to download the track.
