doylebaby gave me the letter B.
Should you wish to play, ask and I will give you a different letter.
'B' is a lovely letter to have been given, as I was quite spoilt for choice. However, I have gone with the band that was the first one to pop into my mind: Bay City Rollers (a real blast from the past) and the song I always equate most with them Bye Bye Baby from 1975.
