Please visit www.soundexperience.co.uk to hear what I sound like...I am in my twentieth year as a solo entertainer for the elderly.  I sing songs from old time music hall, through to popular jazz standards through to war songs through to rock and roll and Beatles, even some James Taylor!  Not much past 1970 though!  I play for 60 minutes, with or without a break - Nursing Homes, Aged Persons' Homes, Day Centres, Friendship Clubs, Hospitals, Over 50s clubs, etc.
